In the most basic definition, plyometrics refers to jump training. Known to be a key component of many sports, such as basketball, soccer, gymnastics, and football, plyometric training can enhance athleticism, strengthen the most powerful muscles in your body, and much more.

Here are some of the benefits of plyometric exercises, and how to safely add plyometrics to your workout routine.

The Benefits of Plyometrics

For you to propel your body off the ground and land safely, many things have to happen in your muscles, tendons, ligaments, and joints. Studies show that plyometrics can help you build muscle as effectively as conventional weightlifting, and if you combine the two, it can help you reach your goals faster than focusing on either one alone. Also, the impact your body absorbs from landing has benefits for your bones: they become stronger.

If you are an athlete, plyometrics can improve your agility and explosiveness when it comes to fast-response moves, such as sprinting, quick direction changes on the field or court, and jumping (such as going for a header in soccer).

How to Get Started with Plyometrics

If plyometrics is new to your workout, as with anything you should start small. This is especially important for plyometric exercises. Correct form is crucial, as you need to both lift your body off the ground and control the landing. This dual action makes plyometric exercises more difficult and complex than most exercises. If you have a movement deficiency, it will be magnified when the speed and power of a jump are applied to it.

When learning a new plyometric move, you should first perform the move without the jump to perfect the form, strength, and stability that is required to do it correctly. Once you have all of that, you can then add the jumping movement. Another way to start small is to choose lower-impact plyometric exercises, such as jumping jacks, jumps in place, and line hops (side to side, forward, and back).

Do not ignore the upper body: plyometric pushups and medicine ball throws are great for building explosive power above the waist. Always be aware of your form. When you become tired, your form tends to suffer, and the risk of injury increases.

Is there anyone who shouldn’t do plyometric exercises? The short answer is no, as long as your doctor has not identified a reason why you should not (such as deteriorating joints or bad knees). If you are significantly overweight, gradually adding plyometrics is the key—and stay away from high-impact moves altogether. Remember that doing too much too soon—or doing advanced exercises before you are ready for them—can stress your joints, increasing your risk of injury.

A while back I shared this blog with six reasons to run with a group rather than alone. Here are six more reasons.

• Group running can help with boredom. Although sometimes alone time is nice when running on your own, group runs fly by much faster. You are more likely to explore new routes when running with a group, which will definitely make your runs more interesting.
• You will feel a sense of community. Whether you are racing together, volunteering at a race, or cheering on your teammates, it is enjoyable and rewarding to be connected with likeminded people and to be part of something bigger. Runners can really relate to each other and are supportive of one another through running (and non-running) ups and downs. Runners feel certain emotions and find humor in things that only fellow runners can understand. These bonds make runners feel like they are part of a special, tight-knit community.
• You will expand your social circle. Running with a group is a great opportunity to meet people with similar interests. Many people have met their spouse, significant other, or close friends through a running group or club.
• It is safer to run with others. Attackers or harassers are not likely to go after a group. You are less likely to get lost if you are with a group, and even if you do take a wrong turn, you have each other to figure out how to find your way. If someone in the group gets injured or sick, there is always someone there to help.
  
• You will discover new routes. People like to share ideas, and even if your running group friends live in the same neighborhood, you are all likely to come up with different running route suggestions. Sometimes you think you know the area, and all of sudden a friend offers a route that will boost and spice up your running. A single new route or a tweak to an existing one can keep your running mind fresh for weeks. As a group you may decide to travel to different spots and explore them when running. Individual runners tend to drive to different locations away from home to explore and experience different running scenery. 
• Entering team events is easier if you are part of a running group. Being a part of group running puts you just one application form away from racing events. The entire group is unlikely to be granted places behind the start line at the coveted Indy Mini Marathon, but there are many races across most of the countries in the world where a bunch of friends can have a great day out. Cross-country is a firm favorite everywhere, but there are also races where you will be running laps, and relay races where you are taking turns with your friends, each running a certain distance. Friends can also join ultra races where you can run, walk, eat, rest, walk, then run some more (if you still can) for anything from 50K onward. There are multiple options out there. Get busy and have fun!

You may have seen the crazy events where men and women lift giant stones, carry logs, and pull vehicles. Did you ever think that this type of training might be exactly what you need to do to have better fitness results? Strongman workouts aren’t as intimidating as they seem. Let’s look at the benefits of Strongman training, and why you should start incorporating it into your training program.

Muscle Mass Gains

There are two important factors in muscle mass building. First, you want to apply the strategic tearing down of the muscle tissue and the subsequent rebuilding via nutrition and rest. Strongman workouts provide the right amount of wear and tear on the muscle tissue to safely tear it down so that it can be rebuilt bigger and stronger than before. Second, growth hormone levels in your body enable a better recovery state and directly influence muscle growth. Heavy lifting, which is what Strongman workouts are all about, has been shown to result in a higher release of growth hormone, which can support muscle mass growth.

Increased Strength

When these athletes are carrying giant logs and moving Atlas stones, it almost goes without saying that they will notice changes in their strength levels. Strongman workouts are based on compound and functional movement patterns, which use several major muscle groups at the same time. Include this with a heavy weight load, lower repetitions, and higher sets, and you are likely to see strength gains. Studies show that Strongman workouts are just as effective as traditional resistance-based workouts at improving your strength levels. However, it’s not just your major muscle groups that will see the benefit; your grip strength will also improve a lot.

Improvement on Functional Movement Capacity

With a powerlifting workout, you are focusing on three exercises that begin at Point A and end at Point B. Many Strongman exercises take place in different planes of movement, which can help your day-to-day functional movement patterns. For example, when performing the Farmer’s Walk, you are holding heavy dumbbells or kettlebells and walking across the floor for a prescribed distance. Another example is carrying an Atlas stone; again, you are holding a heavy weight with proper posture and moving that weight. This translates into real-world benefits such as when you are carrying groceries, playing with the kids, or doing chores. Improving your functional movement capacity will result in a higher quality of life and a lower risk of injury.

Accelerated Fat Burning

As mentioned above, Strongman exercises activate several major muscle groups simultaneously. For example, the sled drag involves the quadriceps, hamstrings, calves, glutes, hip flexors, chest, arms, and core. That is a lot of muscle groups for one movement. The more muscles you use and the greater the intensity during the exercise, the more calories you will burn. Strongman workouts allow you to build muscle mass while helping you lean out. Studies show that compound movements, such as Strongman exercises, can help promote fat burning.

Smashing Through Plateaus

If you have been lifting for a while and you feel as if you are not progressing, consider Strongman workouts. The Strongman style of training pushes you outside of your box, challenges your muscles in a new way, and can potentially help you smash through your plateau. Incorporating a Strongman workout in place of your current traditional resistance training program will introduce a new set of stimuli for your muscles to adapt to. The heavy loads, unique movements, and overall demand on the body should be just what you need to see increases in strength, size, and power.

Preventing Injuries

Strongman workouts help build muscle mass that protects your internal organs. These workouts form strong connections between the muscular and central nervous systems. Most importantly, Strongman workouts strengthen the core, which is where all movement originates and where most injuries occur. A weak core is a recipe for bad news. Lower-back pain is the most common complaint in modern-day doctors’ offices. While the cause might be from a direct injury, most lower-back pain is the result of a weak core and overcompensating muscles. Strongman workouts strengthen the major muscle groups, improving your functional movement patterns and preventing injury.

Easy Transition to Other Sports

One of the benefits of Strongman is that this type of training is not limiting. You can use Strongman workouts as a foundation and then hop to other forms of training such as powerlifting, bodybuilding, or CrossFit. Everything you learn and do in Strongman will apply to many other forms of sports, training, or physical activity. With Strongman workouts, you are simultaneously building a lean and muscular physique, which makes it ideal for bodybuilding. You are also developing incredible raw power, which is ideal for powerlifting. Finally, the explosive strength you gain will be useful in a CrossFit WOD (workout of the day).

If you are a beginner, intermediate, or advanced in your fitness journey, consider starting to add Strongman training to your fitness program in some shape or form. You will be able to build a strong foundation for your fitness routine that will benefit you for years to come.

The New England Journal of Medicine published a study of adults showing that the average holiday weight gain was .37 kilograms, or just under a pound, and more than half the people in the study stayed within a kilogram, or just over two pounds, of their other weigh-ins. Now that the holidays are over, you can lose that weight and stay healthy during the long colder months. Here are five healthy habits to get started with.

1. Do make a plan to manage your stress level.

A good place to start is finding ways to ease stress and anxiety when they occur, or even before. That may mean doing yoga or meditation, taking a hot bath or shower, listening to music, or even just calling a friend to catch up.  Just 10 minutes of stress relief can help you feel more relaxed and make it less likely that you will turn to food. If you’re having trouble finding time to unwind, mark a daily 10-minute stress break on your calendar and tag it with an alert—then treat it like you would an important appointment and don’t miss it.

2. Don’t skip meals to “save up” for a big dinner.

Some people skip meals to “save up” calories for a big dinner or party, but this approach may backfire and lead to overeating later. Instead, limit your intake to an eight-hour window of time each day. This has been shown to be an effective weight-maintenance strategy. You can even try having a lighter breakfast and lunch at your usual times, making sure they incorporate a lot of vegetables and proteins with minimal carbs. For example, you might have a cup of Greek yogurt for breakfast, a green salad with grilled chicken and light dressing for lunch, and then let yourself enjoy the evening feast.

3. Do eat your foods in a specific order.

It helps to have a plate of salad or vegetables before anything else. These low-calorie and high-fiber foods will help you fill up before you dive into the higher-calorie options. Next, have some type of lean protein. If you are going to have carbs (such as potatoes, chips, rice, pasta, bread, or a sweet dessert), save them for the end of your meal. By then, you’ll be less hungry and the protein you’ve eaten will slow your digestion a bit, so you’ll feel full for longer afterward.

4. Don’t forget that beverages count.

An easy way to cut calories is to avoid drinks like regular soda, juice, coffee drinks with added sugar, and alcoholic beverages. Also, try to aim for six to eight glasses of water per day. If you do decide to drink alcohol, choose spirits mixed with something without added sugar, such as seltzer or diet tonic water, rather than beer, wine, or mixed drinks. Or stick to a drink that has only about 100 calories per serving. Do keep in mind that alcohol can lower inhibitions and make you more likely to indulge, so limit yourself to one or two drinks, and have a glass of water after each one.

5. Do give in to your cravings (somewhat).

Controlling diet and weight is a balancing act. Completely cutting out dessert and sweets is simply unrealistic. This can lead to binging or eating more than you’d like to. If you are really craving your favorite sweet, let yourself have some. Remind yourself that this won’t be your last dessert ever and try to put the fork down after one slice—or a few bites, if you’re satisfied by that.

Running with others is one of the most effective strategies for creating a running habit and continuing it. The social benefits of running are among the biggest reasons why runners start and stick with running. Whether you’re running with one friend or a running group, here are some ways you can benefit from group running.

• You’ll have group role models. People naturally start to adopt the habits of those around them. Spending time with other runners will help you form a running habit because you’ll start to mirror your running friends’ habits.
• You’ll motivate each other. With a running group, you get regular encouragement. Members encourage each other at races and during long runs. You’ll be more motivated to stick to your training because you’ll hold each other accountable. It’s harder to skip a workout when you know others are waiting for you.
• You’ll feel a sense of belonging. Being part of a cohesive team can you give a sense of purpose and help you make new and meaningful connections.
• You’ll get creative stimulation. It’s fun to share ideas when running with a group. You can bounce ideas off your running friends and ask them for advice.
• Your performance will improve. Everyone flourishes with a little healthy competition. When you’re running with others who are pushing you to run faster and harder, it’s easier to take it to the next level. When running alone, you may be tempted to cut your workout short; when others are depending on you, however, you’ll want to do the entire workout, and maybe even a little extra.
• You can network. Running with people you know is a great way to network and build your professional relationships in an informal way. You’ll develop a camaraderie with other runners that’s difficult to replicate in an office or other work setting. Building and strengthening relationships through running may lead to a new job or other opportunities. Many runners have found new jobs or made important professional connections through running.

Trying to figure out the best time to work out can be a difficult decision when attempting to balance a healthy lifestyle with work, a social life, and other hobbies. Let’s look at the various benefits of working out at certain times of the day compared to others. 

Morning Workouts

Let’s start at the beginning of the day, or morning workouts. The first benefit of working out at this time is that you will already have your workout done for the day. This should give you a sense of accomplishment to start the day and invigorate you for the day ahead and should also make you feel good and boost your confidence, knowing that you have gotten your workout in, leaving the rest of the day available for other tasks such as working, relaxing, hobbies, cooking and eating dinner, or hanging out with friends.

Some studies have shown that working out in the morning provides an increased metabolism, which means that you are going to burn more calories throughout the day. Another study showed that you will get better sleep working out in the morning compared to afternoon/evening because of an increased heart rate and body temperature. Yet another study showed that working out in the morning on an empty stomach before breakfast could increase fat burning.

Afternoon or Night Workouts

The next option for working out is an afternoon/night workout. If you have to be at work very early, it can make workouts difficult to do, especially if your work starts before a club is open. Early workouts are also difficult during the winter months when it’s dark in the mornings. So working out in the evening or afternoon has its benefits as well.

One study shows that your body temperature increases throughout the day, which is good for muscle function, strength, enzyme activity, and endurance for performance. Between 2pm and 6pm your body temperature is at its highest point in the day, which means your body is ready to go, which in turn makes it the most effective time of day to work out. Oxygen uptake is faster in the evening, as well, meaning that you use your body’s resources in a more effective way than in the morning. Working out in the morning may take your body longer to warm up the muscles, which will take away time from the workout itself. Your reaction time is at the quickest in the afternoon and evening. Your heart rate and your blood pressure are the lowest, which decreases your chance of injury while improving performance. One study even found that if you worked out in the morning and did the same workout at night, you had better quality of sleep.

So What's the Best Time to Work Out?

Overall, based on the above-referenced studies, there is no evidence that working out at a specific time of day is more beneficial than another. Whenever you work out, doing so is important for living a healthy lifestyle. Try to decide what time is best for your schedule to get a workout in, and then try to stick with a time so that you can be consistent to see even more training gains.

Hormones have an especially important role in dealing with resistance training. The endocrine system is a collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, sleep, and mood. Some of these hormones are anabolic, which promote tissue building, and others are catabolic, which are used to degrade/break down cell protein. Ideally for muscle building, it is important to produce anabolic hormones while limiting the production of catabolic ones.

Anabolic and Catabolic Hormones

Scientists have identified examples of anabolic hormones in the human body. These examples include insulin, IGF-1 (insulin-like growth factor), testosterone, and growth hormone. On the other hand, the catabolic hormones are cortisol, catecholamines, and progesterone. For our purposes, we can focus on two of these hormones: testosterone and cortisol.

Testosterone

Testosterone is the primary androgen hormone. The way to promote testosterone is short rest periods, 30 to 60 seconds, heavy resistance—85 to 95 percent 1RM (large motor units), and chronic resistance training (2+ years). Further, testosterone has a known effect on the nervous system: it increases neurotransmitters, and it acts on every tissue in the body. Men have 15 to 20 times more testosterone than women, and acute, or sudden, increases following workouts are small.

Cortisol

Cortisol, on the other hand, converts amino acids into carbs and breaks down proteins and inhibits the synthesis of proteins, which is bad if you are trying to build muscle because proteins are the building blocks for muscle. Cortisol increases during exercise with high volume/short muscle rest, causing large serum cortisol. This does more damage to the muscle and is not good for muscle recovery. Chronically high cortisol levels have adverse catabolic effects.

Knowing that your body produces both testosterone and cortisol, the difficulty lies in the ability to produce more testosterone than cortisol to see muscle growth.

Ways to Promote Lower Cortisol Levels

Here are four ways to lower your cortisol levels so that you can build muscle:

• Utilize proper rest times during high-intensity resistance workouts.
• Eat enough protein and carbohydrates to help you through the resistance workout.
• Perform resistance workouts when your body’s cortisol levels are lower, typically later in the day.
• Make sure you are getting enough sleep.

***

Make sure you are paying attention to your hormones during resistance exercise. If you are not careful, hormones might be affecting your gains in a negative way instead of a positive way. As you can see from this information, these are just a few areas you can target to start producing testosterone and therefore, affect the tissues within your body. Hopefully, this information gives you a better understanding of the main two types of hormones, anabolic and catabolic, how they work in your body, and ways to achieve those gains you are looking for in your resistance training.

Improving maximal aerobic capacity, aka VO2Max, as well as lactic threshold can have a huge impact on overall performance. You can improve VO2 max through long slow distance (LSD) training, pace and tempo training, interval training, high-intensity interval training, and fartlek training.

Training by Experience Level

Training to improve your aerobic capacity varies according to your experience level:

• If you are just starting to train to be an endurance athlete, I suggest that you stick with a long slow distance training until you build your aerobic base, which would be more for mileage/time rather than overloading your lactic threshold and VO2 max.
• If you are an intermediate endurance athlete, you should add one hard workout day (pace or tempo interval, high-intensity interval, or a fartlek) and a higher-mileage day than your usual LSD mileage.
• If you are an advanced endurance athlete, train one or two days with the pace and tempo interval training, high-intensity interval training, or fartlek training. You should also have a high-mileage day that is higher than your LSD days.

Training by Goals

Keep in mind, all this training is also dependent on your training goal. For instance, if you are training for cycling, a full marathon, a cross-country or track event, or are a casual aerobic athlete, long-distance rower or swimmer, and so on, you will want to make sure to have a plan with your goals in mind. Be sure to implement these training methods into your program so that you can hit your goals.

Aerobic capacity and lactic threshold training modules can be tailored to your individual goals and training program. Here are some examples and how they can apply to your training.

• Long slow distance (LSD): Should be race distance or longer and 70 percent of VO2 max, give or take.
• Pace and tempo: Should be done in durations of 20 to 30 minutes at lactate threshold or slightly above.
• Interval training: Should be done 3 to 5 minutes with a work-to-rest ratio of 1:1, and it should be close to VO2 max.
• High-intensity interval training: Should be 30 to 90 seconds with a work-to-rest ratio of 1:5 and greater than VO2 max.
• Fartlek: Has a duration of 20 to 60 minutes and varies between LSD and pace and tempo training intensities.

Keep in mind, some of these norms and training intensities are meant for aerobic distance athletes and are specific to how the training should be done.

Overall, I highly encourage you to play around with these training philosophies and develop it into an aerobic endurance program that is best suited for you. It’s easy to just go out and do the aerobic activity day in and day out, but if you have a more organized, structured program, you will not feel overwhelmed and you will see the gains in your aerobic performance that you have been looking for all along.
