A happy mind is a healthy mind. Here are three keys to working your way toward a healthier life.

1. Show Gratitude

One way to retrain your brain to feel more gratitude and happiness is taking pen to paper. Write down three things about your day that were positive and make you feel thankful. By doing this, you are shining a light on the good things in your life, which shifts your focus and will eventually lead to a healthier mindset.

2. Make Movement a Priority

According to the Mayo Clinic, being active for about 150 minutes a week can result in a drop in depression in most people. Examples of daily activity can be taking your dog for a walk, taking the stairs, working in the garden or backyard, or doing a bodyweight mobility flow to loosen up your muscles and joints. Whatever the activity, make sure you do some movement each day to get the blood flowing and your endorphins boosted.

3. Act in Kindness

Shifting your focus on others instead of just yourself is a great way to boost happiness. Spending time on others has been proven to be more helpful in creating a positive life than spending it just on ourselves. Examples of acts of kindness can be volunteering at a local shelter, running errands for a friend or family member, helping a friend move into a new house, or even buying a cup of coffee for the person behind you in line. Time spent on others is time well spent!

I am often asked what is a good warm-up routine, and my answer typically consists of, “it depends.” A warm-up is typically done at the beginning of a training session and involves low-intensity movements to help get your body ready. The reason I tend to say “it depends” is that your goals, limitations, and what kind of training you have planned for a specific day will dictate your optimal warm-up.

Tailoring Your Warm-up

Now, a warmup does not have to be something innovative, but you do want to perform movements that will mirror your actual workout session. For example, if you have a lower-body day, I would recommend warming up with lower-body movements (and the same for the upper body).

How Long Should a Warm-up Be?

The time a warmup should last can range from 5 minutes to 10 minutes depending on how you are feeling that specific day. If you feel ready to go or have a time limitation, staying closer to that 5-minute limit would be best. If you are feeling a little tired and have no time restriction, then closer to 10 minutes would work better.

Sample Warm-ups

Here I provide a quick sample warmup for a lower-body day and an upper-body day. I do want to emphasize that this is a very basic warmup and it is not meant to fix any compensation that you may have.

Lower-body Warm-up

Perform 2 rounds for 10 repetitions for each exercise. If an exercise is unilateral, perform 10 repetitions for each side.

1. Glute Bridge x 10
2. Glute Bridge with Marches x 10e
3. Downward Dog x 10
4. Shoulder Taps x 10e
5. ½-Kneeling Hip Stretch x 10e

Miniband Series: Perform 10 repetitions for each exercise. If an exercise is unilateral, perform 10 repetitions for each side.

1. Squat (miniband around top of knees)
2. Standing Marches (miniband goes around shoes)
3. Standing Hip Circles (miniband goes around ankles)
4. Lateral Walks (miniband goes around ankles)
5. Monster Walks (miniband goes around ankles)

Upper-body Warm-up

Perform 2 rounds for 10 repetitions for each exercise. If an exercise is unilateral, perform 10 repetitions for each side. You will need a Superband for this as well.

1. Sidelying Thoracic Rotation
2. Downward Dog
3. Superband Chest Press
4. Superband Chest Fly
5. Superband Pull Apart

As you can see, you do not have to reinvent the wheel when it comes to the warm-up, but you do want to make sure that the warm-up will get you ready for your workout.

VO2 max testing, or graded exercise testing, is a treadmill run or cycle to volitional fatigue—or pretty much going until you must stop. The test will tell us how many liters of oxygen you are able to take in and use for cellular respiration.

Physiologically, people use oxygen for a variety of things. The main purpose is for the oxygen to get into the cells’ mitochondria so that it can be used to generate adenosine triphosphate (ATP), which is the main energy source in the body. People use ATP to do pretty much everything: move our muscles, think, and even digest food. So the more oxygen you can take in and convert to energy, the longer and faster you can run due to this surplus of energy you are making at the cellular level.

What the Test Is Like

The test starts at a low speed and no incline on the treadmill. Then every so often the treadmill gets a little faster and a little higher. The increases are almost unnoticed and most start out walking. On the other hand, on the cycle, the resistance gets a little harder occasionally and the participant is expected to maintain the same rotations per minute (RPM). With both tests, the person is expected to go until they feel they must stop, when their workload is too great to maintain or their legs become too fatigued to continue.

What the Test Measures

While exercising, you will be hooked up to different devices to monitor your vitals such as a heart rate monitor and a ventilator of sorts. Some tests will also measure blood pressure and rate of perceived exertion. Trainers can use the information from these devices to generate a customized endurance program for you to push you to increase your VO2 max, and in turn, your overall endurance. VO2 max testing is a great way to know where you are currently at in your endurance training. It is comparable to doing repetition max testing on weights in strength training.

How the Results Can Shape Your Training

Trainers can utilize the data from a VO2 max test to make a program customized to your physiology. From a VO2 max test we can see what your heart rate maximum is exactly, and using these numbers we can get more accurate training zones for you. The ventilator gives a variety of useful data such as your aerobic threshold, or the point when you really start to breathe hard. This is the point where a person really starts to hate running, so knowing this point can help us stay below that more often, making the training more enjoyable while still receiving the benefits. Knowing different heart rate zones can help prevent overtraining and help push you to your fullest capacity, causing your body to adapt and consume more oxygen.

The measurements of blood pressure and perceived exertion are more common in a clinical setting to ensure normal responses to exercise, so they are not always necessary in healthy populations. The trainer can use rate of perceived exertion, however, to know how a person feels at certain running speeds. If someone feels that they are working very hard at a faster speed, the trainer may stay below that speed more often to make the runner more comfortable; and if a certain speed feels very easy, the trainer may ramp up the pace.

VO2 Max Testing at NIFS

Korr CardioCoach metabolic system VO2 max testing is offered here at the National Institute for Fitness and Sport. Connect with a trainer at the track desk if you have any interest or questions. VO2 max testing is a great way to gauge your endurance level going into marathon training, and a great way to pace yourself in a race by knowing where you are at physiologically at different workloads. Knowing your VO2 max as a runner is like how a powerlifter knows what the maximum amount of weight they can bench is. If you don’t have a benchmark going into a competition, you run the risk of over- or under-shooting and not performing as well. You don’t necessarily have to partake in a full VO2 max test if you are concerned about going to volitional fatigue. There are submaximal tests and estimation equations that can be utilized to get a rough estimate of your VO2 max. See a NIFS staff member with any questions you have pertaining to a VO2 max test or to schedule your test today.

How many times have you or someone you know needed help because they were unable to open the pickle jar? Now, how many times have you heard someone get mad because the pickle jar was too easy to open. I’m guessing you haven’t. Nobody has ever complained about being too strong—a statement I like to tell people when they ask why they should start strength training. There are many benefits of strength training. As we age we lose the physical ability to carry out certain activities. Tasks that were once easy are now difficult to do alone or not at all. These are our activities of daily living. 

Activities of Daily Living

Your activities of daily living (ADLs) are your everyday activities that are essential to get you through the day: walking, getting up from chairs, carrying groceries, bringing in the bag of dog food, and so on. As a person ages, these activities get harder and harder to carry out. According to Harvard Health, it is estimated that after the age of 30, a person will begin to lose 3–5% of their muscle mass per decade. Loss of muscle mass will result in the loss of your ability to carry out your ADLs. Additionally, with loss of muscle comes the loss of muscular power, or the ability to produce force quickly. The loss of muscular power is the main contributor to the increase of fall risk as we age.

The loss of muscle mass as we age is termed sarcopenia. Age-related loss of muscle is, of course, preventable. With the correct diet, exercise plan, and regulation of hormones, a person can not only maintain but also increase their muscle mass as they age. This will ensure that you are able to maintain your ability to perform those ADLs with no trouble. Things such as yard work and playing outside with kids or grandkids are activities that should never be lost.

Athletics

Switching gears now to a different population. All aspects of strength are required to excel in a particular sport. From field sports to court sports to endurance running events, being strong will help everyone. The primary benefit that all athletes gain from strength training is an increase in joint stability. A well-structured resistance training plan will not only make the muscles stronger, but will also progress in a way to allow time to increase tendon strength at the same time. A more structurally sound joint is less likely to get injured.

Force is an influence that can change the motion of an object. Force is how we walk, jog, run, jump, change direction, and everything else we do in sport. There are two components that go into force, mass and acceleration. From a training aspect, we can manipulate these two components to match our needs. How this translates to the weight room is, we can move a light weight fast, or move as much weight as we can. Both forms of training will increase force production in their own way. Each athlete will need to train at different ends of the force curve depending on their sporting event and their biology. It is up to the strength and conditioning coach to make a plan for the individual’s needs and sport.

But I Don’t Want to Be “Bulky”

The common misconception is that resistance training will make you “bulky.” I only have one response to this question every time I get asked. I tell people to look at how track athletes and wrestlers train. These athletes are at peak performance but must maintain, and even in some cases lose, body weight. They do this by resistance training with very heavy loads for very low repetitions. This type of training increases muscular strength without increasing muscular hypertrophy (muscle size). If your goals are to increase strength and maintain your muscle mass, training with heavy loads and low volume is the route to take. This approach is also how powerlifters train. Their goal is to increase the amount they lift at a competition, but they must stay within their weight class. They cannot gain excess weight or else they will have to compete in a higher weight category.

The bodybuilders that you see at the very top level spend years and years building up their bodies to look the way they do. They train daily on individual muscle groups to sculpt their body to look perfect for the judges at a competition. Bodybuilders work in a higher-volume rep and set range than that of a strength athlete. Over an extended period of time, with the right diet, recovery habits, and in some cases the use of performance enhancers, bodybuilders are able to look the way they do when they step on stage. However, strength training two to four days a week to improve your health will not make you look like a “bulky” bodybuilder.

Strength Training Is for Everyone

Being strong is never a quality that someone wishes they did not have. A simple strength training regimen will not make you bulky, or weigh you down for everyday tasks. It will make you stronger and healthier. It will give you confidence to do new things, or things that you have been unable to do or wish you could do. Strength training will give you the ability to play with your kids, and then your grandkids after that in the same way. Not everyone wants to be a bodybuilder or a powerlifter, but everyone wants to feel good in their own skin. After all, nobody has ever complained about being too strong.
