Starting your fitness journey is always an exciting step forward, but it is essential to make sure you are listening to your body and prioritizing your recovery and self-care. Many people tend to neglect their bodies' needs and push themselves past their limits, which isn’t necessarily a bad thing. The importance of recovery and self-care play a crucial role in ensuring your long-term success in the gym, and one mistake can lead to a possible injury that can take away and/or limit that progress.

The Importance of Recovery

Recovery is one of the most important aspects of any fitness regimen. Giving yourself enough time to recover helps your body repair and strengthen itself. Without giving the proper recovery your body needs can lead to a higher risk of fatigue, decreased performance, and increased risk of injuries. Here are a few key components to ensuring you have an effective recovery period:

• Rest Days: Incorporating rest days is essential in allowing your body to heal and grow your muscles. You typically want to aim between 1-3 times a week depending on your fitness level and intensity for your workouts, so it may vary from person to person.
  
  
• Sleep Quality: Quality of sleep is a must for effective recovery. Anywhere between 7-9 hours a night is optimal to support muscle repair, hormone balance, and overall mental and physical health. Maintaining a consistent sleep routine will help manage your body's recovery each day.
  
  
• Hydration and Nutrition: Proper hydration and nutrition play a significant role in your body’s growth and recovery. Ensuring that you are drinking plenty of water during the day, and focusing on a balanced diet with protein, healthy fats, and complex carbohydrates will keep your body properly replenished and aid in muscle growth and repair.

Self-Care Practices

• Mobility and Stretching: Practicing stretching and focusing on mobility work regularly can help enhance flexibility, reduce muscle soreness, and prevent injuries. Incorporating dynamic stretching before workouts and static stretches after workouts helps maintain your muscle's elasticity and joint health. This can help with knee pain, lower back issues, and posture over time.
  
  
• Mindfulness: Mental wellness is just as important as physical wellness. Practicing mindfulness can help reduce stress, improve your focus, and enhance your overall well-being. Focus on relaxing the mind for a few minutes a day to help clear your head, such as deep-breathing exercises to calm the mind and body. This can be paired with your static stretches to help your mind and body at the same time.
  
  
• Active Recovery: On rest days, engaging in active recovery activities such as swimming, biking, yoga, or walking can help promote blood flow, reduce muscle soreness, and aid in muscle recovery without straining your body. Ensure that you are keeping a low intensity when engaging in these activities.

Prioritizing your recovery and self-care can play an important role in enhancing your performance, maintaining a balanced lifestyle, and helping prevent injuries. These practices will not happen overnight and will take dedication and time to achieve but will help you in the long run. Embrace, motivate, and stay consistent, and embark on your fitness journey prepared and ready to take on any challenge.

If you're unsure where to start or want to ensure you have the right balance between your fitness goals and recovery, or if you're simply looking to work with a professional, NIFS offers personal trainers who can help guide you every step of the way. Take the next steps with the support you need!

Running in the summer can be a pleasantly dangerous experience! As the sun shines and temperatures rise, the risk of heat-related illnesses increases. Listening to your body and adhering to the following recommendations will not only help prevent heat-related illnesses but make summer running an enjoyable experience!

1. Timing and Planning

The coolest parts of the day tend to be mornings and evenings. If you are planning to run, be proactive and look ahead at the weather forecast. Planning your runs at these times of day will limit the risk of excessive heat exposure. If you must run in the heat of the day, plan a mostly shaded route to limit sun exposure.

2. Find Your Happy Pace

Running in the heat naturally puts more strain on your body leading to increased heart rate. In many cases, runners are unable to sustain their regular paces in hotter conditions. If this occurs, settle into a slower pace that feels comfortable and sustainable to you.

3. Hydration & Electrolytes

Hydration is key in summer running. Increased sweat is associated with increased temperatures. Drinking an adequate amount of water before, during, and after your run is crucial in preventing dehydration. I would recommend drinking at least ½ your body weight in ounces of water to ensure proper hydration. Electrolytes are essential nutrients our body expels in the form of sweat. Consuming an electrolyte drink, banana, or salty snack after a run can help replenish the contents lost in sweat.

4. Listen To Your Body

Knowing and recognizing the signs of heat illness are important when embarking on summer runs. Symptoms of heat exhaustion include dizziness, headache, nausea, and weakness. If these symptoms occur, find the quickest way to cool off immediately. Symptoms of heat stroke include high body temperature, rapid pulse, and confusion. If these symptoms occur, seek medical attention immediately.

With the right approach, running in the summer can be a safe and enjoyable experience! Make sure to check the weather, plan runs during cooler times of day, adjust your pace, and recognize the signs of heat illness to ensure safety during these warmer months. Stay cool, and happy running!

Roughly how many hours of sleep would you say that you average per night? Six hours? Ten hours? Now think about your fitness goals and the results you want to see from exercising. Are you where you would like to be, or are you on pace to get to where you would like to be? You can be doing everything correctly from the exercises that you perform, nutrition and supplementation, stress reduction, whatever it may be, and you aren’t quite getting the results you’re looking for.

The Stages of Sleep

What if I told you that the amount of sleep that you get in a night correlates to your recovery from exercise? In most cases, it is recommended that you get at least eight hours of sleep per night. This can vary depending on factors such as exercise intensity, frequency, and even your age, however. For the purpose of recovery, let’s stick with that eight-hour recommendation. Why is that the recommendation? There are four stages of sleep that cycle throughout the night. There is N1, N2, N3, and REM. Reaching N3 is essential for recovery, and it is important that your body spend enough time in N3 while the sleep stages are cycling. During this N3 stage of sleep, the body releases hormones that are essential for recovery at night. One of the hormones being released is Human Growth Hormone (HGH). HGH is essential because it acts on many tissues in the body, muscle tissue being the big one, and it helps promote healing and recovery. HGH also helps raise other hormones in the body that are essential to recovery such as Insulin-Like Growth Factor (IGF-1).

How Do You Know Whether You Are Getting N3 Sleep?

As I have said, these sleep stages are constantly cycling throughout the night. Have you ever had multiple dreams in a night? That likely means that you reached REM sleep at least twice that night, which is great because your body got enough time in a deep sleep state and enough time in that N3 stage. Back to that eight-hour recommendation. Although this can vary slightly, it has been found that sleeping eight hours allows the body to go through two to four sleep cycles on average, therefore giving the body enough time in N3 and enough time for the essential hormones to be released.

If you’ve been into fitness for a while, you likely know how important it is to fuel and replenish your body before and after exercise with the proper nutrition. However, you might be uncertain and confused about why, when, and what to eat and drink to optimize your workouts.

Before Exercise

Why: When digested, carbohydrates are turned to glucose, the body’s main energy source. Consuming a moderate-to-high amount of carbohydrates depending on the type, duration, and intensity of exercise will help you maintain consistent energy levels throughout. Additionally, adding a moderate amount of protein to your pre-workout meal or snack can “prime” your muscles and may help prevent muscle breakdown during exercise.

When: Within 1–3 hours of exercise (typically)

What: Moderate to high carbohydrate, moderate protein, fluids

Examples: Apple or toast (carb) with peanut butter (protein), Greek yogurt (protein) with berries and/or granola (carb), string cheese (protein) and crackers (carb), etc.

What NOT: Avoid fatty/greasy/fried, spicy, and fibrous foods because they may cause stomach upset during exercise.

After Exercise

Why: After exercise, you must replenish the carbohydrates used for energy and consume plenty of protein to aid in muscle repair. The more energy you use during exercise, the more carbohydrates you will want to replace. Similarly, the harder you work your muscles, the greater strain you put on them, the more protein you will want to consume to aid in recovery.

When: Within 1 hour of exercise (typically).

What: Moderate carbohydrate, moderate to high protein, fluids

Examples: toast (carb) with tuna, chicken salad, or eggs (protein); Greek yogurt or chocolate milk (protein) with fruit (carb), turkey lunch meat (protein) with veggies and dip (carb), protein shake/bar

All in all, the timing and amount of food required to properly fuel and replenish your body before and after exercise is highly dependent on the individual, the type of exercise being performed, and the individual’s goals. Speak with a registered dietitian to better understand your individualized nutrition needs.

Sports careers, whether you are junior varsity or a hall of fame professional, all come to an end at some point. Often, these endeavors are marred with setbacks due to injuries ranging far and wide and sometimes spanning years. During competition and in the spirit of the moment, athletes sometimes push their bodies and minds beyond what was thought possible, resulting in amazing feats—but also potential injuries.

Don’t Play Through Your Injuries

Injuries that occur when we push our bodies to the limit can become more pronounced when an athlete decides to continue activities instead of receiving timely treatment. Once commonplace, playing through injuries was more accepted in the past. However, with modern sports medicine and advanced technology, sports enthusiasts can enjoy longer, more productive careers than ever before due to increased injury awareness and preventative maintenance.

The adage “listen to your body” still rings true. Although you might not know what you are listening for, you can assess your situation and make smart decisions to help prevent more serious injury.

How Do You Know When You’ve Overdone It?

Symptoms of sports injuries and illness can vary, and anytime you have a serious concern about your health, refer to your primary care physician. Because every person experiences pain differently, resulting in a wide threshold, you may need to seek advice and consult a professional to help assess your situation. Here are some of the most common symptoms of injuries, according to Harvard Health.

• Chest pain: Although this goes without saying, your heart is the most vital muscle in the body. Although coronary artery disease is not curable, treatments make it possible to decrease the chances for heart attacks (which may occur when a deconditioned individual is subjected to extreme strenuous exertion).
  
• Difficulty breathing: Similar to chest pain, difficulty breathing can be a sign of more serious underlying issues with not only the lungs but also the heart and blood pressure. With high blood pressure, exercises such as sprinting and powerlifting typically put a lot of strain on the heart.
• Joint swelling and pain: The swelling of a joint can range from tendon, ligament, or muscle injury to arthritis in the joint. It is good to know whether you are experiencing injury or arthritis because this will determine your level of treatment.

How to Recover and Get Back in the Game

These symptoms are common and can happen to almost anyone who exercises. Many other factors such as genetics, age, and medical history all play a role—not only in your injury, but also your healing process. “Getting back on the horse” is something we eventually want to do (once we are healed).

Here are a few tips that can get you back on the road to recovery without jeopardizing your health.

• Before beginning a new workout program, meet with a fitness professional who can assess your physical fitness levels. Many tests are available, the Functional Movement Screen (or FMS) is designed to not only pinpoint potential red flags, but also to prescribe routines intended to better your movement patterns and decrease your chances for injury.
  
• Beginning a proactive fitness program that targets your weaknesses and strengths can also help decrease your chances for injury. A program that identifies your strengths and uses them is good, but you also need to make sure your weaknesses are addressed. As these weaknesses become stronger, as a whole, you will become stronger.
• Moving your workout to a more low-impact setting might also help. The pool adds a great opportunity to create exercise but not put stress on the joints. We know that swimming takes some skill, but just treading water can be a great way to burn calories. Depending on availability, zero-gravity treadmills and water treadmills are often used in the professional athlete world to get athletes moving (technology never ceases to amaze me).

Raise your hand if you’ve been here before: You get to the end of a great workout. You’re spent, fatigued, but in a good way. In a way that you know you’ve put in some quality work. But you look down at your watch and realize you’ve run a bit over your time. So you grab your things and rush out of the gym. You don’t have time for a cool-down, right? You’ve got to get to the car and rush to the next thing on the docket.

Without realizing it, you’ve kept up that same stimulus from your workout: that amped-up, fight-or-flight response. Only now it’s been hours since its conclusion. In short, your body has never left that stress response behind. Instead, it’s been carried around perhaps all day, and your body has not had time to transition into a rest, digest, and recovery mode. In other words, you’ve never shifted from a sympathetic (fight-or-flight) to a parasympathetic state (rest, recovery). This may sound like a “so what?” problem. But if left unchecked, this can not only stall out your workouts, but can also eventually lead to chronic issues with inflammation, sleep problems, or altered hormonal responses.

Appropriately managing your stress response isn’t something that only applies to workouts. We all face stressors on a daily, weekly, or hourly basis (perhaps in today’s world now more than ever!). If it starts to get out of hand, numerous aspects of our health and well-being are affected. Learning to mitigate and manage chronic stress can have positive effects on both physical and mental health. One way to do this is to address your vagal tone.

What Is Vagal Tone?

The longest nerve in the human body is the vagus nerve. It innervates numerous organs such as the intestines, stomach, heart, liver, and lungs (fun fact: “vagus” translates to “wanderer” in Latin; because it wanders around the body). The vagus nerve is a key part of the parasympathetic nervous system, and vagal tone refers to the activity of this nerve. If it is impaired, low vagal tone results, which is a contributor to stress and increased anxiety, a pro-inflammatory response, and a disruptor of normal gut functioning.

What Are the Benefits of Increased Vagal Tone?

A high vagal tone is associated with lower blood pressure, improved blood-sugar regulation, improved digestion, better mood, reduced anxiety, and reduced risk of stroke and cardiovascular disease. Perhaps one of the largest benefits of a higher vagal tone is the ability to relax faster after stress. So whether you’re talking physical stress from a workout or mental stress from everyday life, having an increased vagal tone can help you navigate the stressors of everyday life and be better prepared for the next one!

Additionally, researchers have discovered a positive feedback loop involving increased vagal tone, positive emotion responses, and physical and mental well-being. In short, the vagal response, or parasympathetic drive, actually works to mitigate stress and foster positive emotions. Definitely a win-win!

How Can You Increase Vagal Tone?

Okay great, now how the heck can I start working to stimulate the vagus nerve? Here are a few quick hitters that you can do today to improve your vagal tone.

Deep or Diaphragmatic Breathing

If you have virtually no time to cool down after a workout, a few deep, slow, diaphragmatic breaths can help quickly shift you toward more of a parasympathetic state. Lying on your back, elevating your legs so that your knees are at 90 degrees (on a box or bench), and taking 10–20 slow, deep breaths helps to gradually lower the heart rate and reduce blood pressure, all while stimulating the vagus nerve. Try having one hand on your upper chest and one hand over your belly button, and as you inhale try to see if your lower hand (belly) is moving upward. If you notice that only your upper hand is moving upon inhaling, take a few reps to practice filling your belly with air. This is a skill just like any other; it takes a bit of practice. But if you’re short on time, this technique is a bit of a cheat code. You can even try it before bed to help relax!

Singing, Humming, or Gargling

Yes, you read that correctly. One of the branches of the vagus nerve, the superior laryngeal nerve, actually innervates the vocal cords. As a result, we can mechanically stimulate it by singing, humming, gargling, chanting, etc. So belt out those tunes for car karaoke, hum that song that’s stuck in your head at work, and increase that vagal tone in the process!

Cold Exposure

For all us Midwesterners, we should have this one covered for about 7–8 months of the year! In all seriousness, gradually increasing your exposure to cold, and eventually becoming more habituated, causes a shift to greater parasympathetic activity. This doesn’t mean you need to go out and run two miles barefoot in the snow. You can start by splashing cold water (and I mean cold) on your face 10–20 times. Or going out to get the mail in December in a t-shirt and shorts. Or finishing off your shower with a quick 10-second blast of cold. Overall, try small interventions first to get the ball rolling. And if you’re looking for a laugh, check out my previous blog, when I put myself through hot-cold contrast showers for a week!

Omega-3s

The body cannot produce omega-3 fatty acids naturally, so they must come from the diet. They are found readily in fish (especially cold-water fish like wild-caught salmon), extra virgin olive oil, avocados, walnuts, and flaxseed, among other foods. Their benefits are wide-ranging: they positively affect brain and mental health, mitigate inflammation, and aid in improving cardiovascular health. Studies have also shown that omega-3 fatty acids also increase heart rate variability (a good thing!) and stimulate vagal activity.

Social Interaction

We are social creatures. As humans, we are hardwired to find and belong to a community. So it should come as no surprise that social connection, laughter, and having a stable support system improves our mental and physical health. While this may have been more difficult or a bit unorthodox with COVID-19, its importance has never been greater. Research has shown that laughter increases heart rate variability, and that even reminiscing about positive social connections and prior engagements improves vagal tone and increases positive emotions. So even if you can’t physically be near those you love and appreciate, making that effort to continue to reach out and connect goes a long way in your recovery from stress.

Jump-Start Your Recovery

We all face stressors on a daily basis. Whether it’s the low-level background noise of the news, or a large deadline looming in the future, learning to navigate and respond appropriately to stress is a must for maintaining physical and mental well-being. By increasing your vagal tone, you can help jump-start your recovery so that you’re more ready to tackle the next thing on your to-do list, be it a work project or a workout!

For whatever reason, there seems to be this notion in the fitness industry that if the workout doesn’t leave you on the ground gasping for air, it really wasn’t a good one. Or maybe that you didn’t work hard enough because you didn’t go running to the nearest trash can by the end. This could not be further from the truth; but unfortunately this way of thinking still seems to run rampant.

Not Every Workout Has to Be a Gut-Buster

One of my favorite quotes when it comes to strength and conditioning comes from Yuri Verkhoshansky, Russian professor, coach, and author who is credited as being the father of plyometrics. He suggests that “any idiot can make another idiot tired.” Now, I’m not calling anyone out. But this brings up a fantastic and often forgotten premise: that we should not judge the quality of a training session simply by how exhausted we feel.

Yes, we should challenge ourselves. Yes, there should be times when a workout feels more difficult. But here’s the key: not every workout should feel like a gut-busting knock-down, drag-out fight to the finish. If it does, it might be time to reevaluate.

A Quick Exercise Physiology Lesson: The Aerobic System

Our bodies rely on three energy systems to get us through everything from a tough workout session to washing the dishes, as well as basic organ function around the clock. They are all operating in some capacity all of the time, just in varying degrees based on the activity we’re doing. It’s not like a light switch, just on/off. Here are our players:

• The ATP-PCr or phosphagen system (immediate)
• The anaerobic or lactic system (short term; remember glycolysis?)
• The aerobic system (long term)

Now, this isn’t intended to be a full-blown Bill Nye-esque science lesson. But I do want to focus on one of those energy systems for just a moment because it plays a massive role in how we are able to recover from task to task. And that is the aerobic system. It has the capacity to produce a great deal of energy, ATP—our body’s form of energy currency. The only problem is that is takes a little while longer to do compared to the other two. As a result, the aerobic system is responsible for replenishing and producing energy during rest periods or downtime between bouts of high-intensity exercise.

Much like any facet of fitness, this system can be trained directly. It typically comes in the form of slightly lower-intensity exercise (examples to come in a future post). So, while the exercise session might not feel like a back-breaker, the benefits that arise from it can come back twofold when looking at future training sessions. Essentially, what you’re doing when you are working on bolstering your aerobic system is building a bigger, more efficient engine.

Reap the Benefits of Faster Recovery

So, those high-intensity classes you take a couple times per week? Think about being able to sustain the same power and strength from round to round because you can recover more effectively during your rest periods. Or maybe you like to hop under the bar for some strength training in the form of squat or bench press. Well imagine being able to hit more of those heavy singles because you recover more proficiently between sets. That’s when the aerobic system really kicks into high gear: during rest. Yes, it is always contributing to some degree when it comes to ATP production (remember energy currency?). But its benefits really come to light during the downtime.

Building your fitness profile really requires a 360-degree approach. Some sessions may focus on strength. Some sessions may focus on high-intensity training. And some should take the time to address the aerobic system. Not only do they provide the body some much-needed recovery time; these sessions can also allow you to get more out of those strength and high-intensity workouts as well.

Next time, I’ll cover specific examples of how you can train your aerobic system. Until then, stay strong, my friends!

Do you remember the last time you went on an extended vacation, came back home, jumped into the gym and your favorite class and thought you could pick right back up where you left off? You might remember feeling like you were not going to make it through the class and were so sore for days on end. And that was just after a vacation consisting of a long rest, relaxation, and food freedom. Just think what you may encounter once you return to your favorite class or training group after two to three months of quarantine.

Now if you have been able to keep up your training intensity during this time, that’s awesome, and what I’m talking about might not apply to you. But I would argue that most of us, even with the best intentions, might not have been exercising at the same intensity in which we left our favorite facility. And if you jump back in too fast, at too furious of an intensity, you could find yourself with far worse than a case of sore muscles—and maybe even losing your lunch during class.

As you make your way back into your gym and classes, here are five helpful tips that will aid in keeping you safe and free from injury so you don’t get knocked out for another couple of months.

Reset Your Mindset

I think the most important step in getting back to your previous fitness level is being okay with not being at your previous fitness level. There is no room for negative self-talk because your deadlift isn’t Instagram-worthy right now, or running a mile is now incredibly challenging when it was once a warm-up. Think short-term adjustment at the beginning as you get your legs back underneath you. Find the little victories and be proud of them as you continue to ramp back up to previous intensities.

Start Slow and Add Gradually

Stave off injuries or worse by starting slow and adding intensity progressively throughout the first 8–10 sessions back. Starting off too heavy or too fast can lead to physical injuries as well as emotional setbacks. Build some confidence every session, and you will be back to your prime self in no time, safely! 

Do an RPE System Check

Do a frequent body system check using Rate of Perceived Exertion (RPE) scale. The Borg Scale is a rating chart from 6–20 of how hard you feel yourself working at any one given task. There is a modified version that is a simple 0–10 rating system. Either one correlates well with your heart rate and can provide a quick and reliable audit of how your body is reacting to exercise. If you feel like you are barely moving, you may be at a 6 or 7 (1,2); or if you feel like if you keep up the current intensity you may lose that lunch I mentioned earlier, you may be at an 18–20 (8–10). It’s quick and easy, does not require equipment, and can provide an accurate intensity level check. Do frequent system checks throughout your workout, and if you feel you are pushing to the higher numbers of that scale, you may want to back it down and gradually work up to that intensity level.

Warm Up/Prep for Movement

Take the time to properly warm up and prepare yourself for the work at hand. This message is not new, and should always be practiced, but even more so now that you may have had a lengthy layoff. Consider this as part of your workout and you are more likely to complete it every time; don’t treat it as an option that is nice to do if you have the time. Make time! Foam rolling and soft tissue techniques, dynamic warm-up drills, and stability work should all be completed before jumping into a training session or your favorite class. Five to seven minutes can save you months in rehabbing an injury that could have been avoided.

Hydrate and Recover

Same as above, not a new message but a super-important one these days! Start hydrating now if you have been lacking in that area. Don’t wait until midway through a training session to start fluid intake. If you are following the rule of thumb and ingesting half your body weight in ounces of water daily, you are in a great position. Just like your warm-up, take the time to cool down and perform recovery drills post workout. These will help with soreness and increase mobility while slowing down your mind to focus on the victories you just grabbed in the workout. Slow down the systems and reward yourself for a job well done!

***

We were confident that this day would come when we could get back to our gyms, groups, and classes and get moving like we did before everything changed. Now that it is here, please take the proper steps in protecting yourself against injury or even worse. It may take some time to get back to where you once were, but it will be well worth it!

Nowadays, it seems that many people are trying to find that next great gadget to help put them over the top. Whether it’s the fitness world, life at home, or the day-to-day grind at the office, people seem to be peddling some kind of shortcut or cheat code to help aid performance in some way, shape, or form. I know I can’t go a day without scrolling through Instagram and seeing an ad for some new, expensive toy guaranteed to solve whatever problem I seem to be having that day.

While sometimes it can be tempting to explore those avenues, I usually tend to stay the course and preach the basics when it comes to performance and recovery. Have I slept 8 hours? Have I eaten whole foods? Did I have a sip of water that day, or was it an IV of caffeine instead? Despite all this, recently I found myself continuing to run across the concept of cold showers, or contrast showers, and how they can be used to aid recovery.

I saw articles about athletes like LeBron James using them for recovery. I read articles from the Journal of Strength and Conditioning examining their benefits, both physically and psychologically. I saw them pop-up as topics on a few podcasts that I listen to frequently. So finally I decided, “Why not? I’m going to do a 7-day experiment on myself and give these contrast showers a try!”

What Is a Contrast Shower and How Can It Help?

First, a little background. A contrast shower alternates between bouts of hot and cold water for a total time of anywhere between five and ten minutes. Some of the purported benefits of this cold thermogenesis include the following:

• Improves blood flow and nitric oxide delivery, especially within the brain.
• Reduces systemic inflammation.
• Supports the connection between the brain and the digestive system by strengthening vagal tone.
• Improves appetite regulation.
• Improves insulin sensitivity.
• Improves mood, focus, and attention.

What Happened When I Tried It

In my case, I chose the 10 seconds of hot, 20 seconds of cold version. I alternated between these 30-second segments 10 times for a total of five minutes. Here’s the breakdown of what ensued:

Day 1

I was terrified. I was starting my early morning with a cold shower. However, I cheated a bit and started with 30 seconds of lukewarm water before flipping it straight to hypothermia-inducing temperatures. And it took my breath away when I finally did. I used my arms as a shield. I think I actually screamed at one point (haha). Once I was through two or three cycles, though, it was a lot less shocking. Still not fun, but definitely more manageable.

Day 2

The first two or three rounds were still brutal. My breathing accelerated and I’m pretty sure I was making weird noises too. By round four, I started turning around, 360 degrees, during the cold portion. It helped a bit, purely from a distraction standpoint. The last two rounds I stood stock-still, focusing on my breathing. When I got out, and even 5, 10, and 15 minutes afterward, my mind felt very clear. I felt a little more energized. But maybe that was because I was grateful it was over!

Day 3

This time I rocked it out at the end of my day. Similar to the first two days, the first two rounds were a struggle. However, finding two really good songs to jam to was extremely helpful. I didn’t have to focus as much on how many rounds were left; instead, I just waited for the songs to end. Also, dancing in the shower, albeit somewhat risky, was a heck of a good distraction!

Day 4

I’m probably losing it by day 4, because I was actually looking forward to it today! I liked the clarity it seemed to bring. I liked the way I felt physically afterward. And as alluded to before, picking a killer playlist is key!

Day 5

I almost ditched my 7-day experiment today. Mentally, I was not feeling up to it. But afterward, I’m glad I stuck with it because I felt very refreshed. I could stand under the cold water while staying still and not screaming, even on round one!

Day 6

Today I focused on making sure some of the more temperature-sensitive areas, like the top of the head, underarm, and chest, were hit throughout. This was quite the curveball! That take-your-breath-away temperature hit me like a tidal wave. I was so alert afterward, though, that I almost forgot to make my morning cup of coffee. I was wired and ready to go at 4am!

Day 7

Mama I made it! I went into this one hoping to alleviate some soreness I had from a workout the preceding day. Afterward I still had some stiffness, but it was markedly different. This was at the end of my day, and transitioning from the contrast shower to holding a warm cup of tea and reading a book was incredibly relaxing. While I was alert, I wasn’t amped up. I felt refreshed and focused. And it sure didn’t stop me from falling asleep the second my head hit the pillow about an hour later.

Final Thoughts

By the end of the seven-day experiment, I was oddly “hooked” on the whole contrast shower concept. Although this is anecdotal evidence, I felt calm, focused, and alert after each shower. I noticed small improvements in self-reported soreness as well. And if nothing else, it was a heck of a wake-up call at 4am before work!

It remains to be seen just how much cold thermogenesis can aid in recovery post-exercise, as the current research (and here) is equivocal. But as with many recovery methods, there is something to be said for the perceived improvements in soreness or pain management. In other words, if you think that it’s working for you, then it will. If you think that it’s a waste, then it probably is.

As of today though, I’m currently riding a 17-day streak of contrast showers! Stay cool, everybody!

With the winter months settling in, and maybe traveling becoming part of your routine, it may become harder to carve out time for workouts. Limited access to equipment may also throw a wrench into your plan for a quick training session. But by incorporating bodyweight movements into a flow circuit, you can bypass the excuses and be workout ready any time, any place.

What Is a Bodyweight Flow?

Flow circuits typically include bodyweight movements that are linked in succession one after another with minimal or no rest in between. They can be used as a dynamic warmup, a low-intensity recovery circuit, or an entire workout in and of itself. They can also be a great way to sprinkle some physical activity into your day, especially if time and equipment are lacking.

How to Implement a Flow Circuit

If you’re looking to spice up your standard dynamic warm-up (or add one in general), a simple two-minute flow circuit fits perfectly. You can perform each movement three to five times, and when the movements are linked together in succession, they help increase blood flow, improve mobility, and increase your overall core body temperature to prep you for the workout ahead. Bodyweight flow circuits also allow you to hit large, compound movements that address stability at multiple joints in a shorter amount of time. Overall, they are a great bang for your buck. Examples of movements include bear crawls, cross-under lunges, inchworms, and rocking patterns.

Here are a couple of bodyweight flow options that you can take for a spin next time you’re at the gym in need of a warm-up.
