By this point, everyone has heard that exercise is good for health. The fitness industry has been growing significantly over the past decade. As of 2017, there were more than 200,000 health and fitness clubs worldwide, which is up from nearly 130,000 clubs in 2009. Clearly, fitness is becoming a huge part of peoples’ lives. But why are we seeing this massive growth in the industry, and in what ways is it improving health?

The Physical Benefits

The physical benefits of increased activity include the following.

Increased Muscle Mass

A well-known benefit to working out is increased muscle mass. This alone has so many benefits to your health besides the visual appeal that people seek. Muscle is a huge driver for metabolism. In fact, it takes so much energy to maintain muscle mass that having more of it increases metabolism significantly, even at rest.

Improved Bone Health

Most people hit peak bone mass in early adulthood. After we hit our peak, our bone density begins to decline. Several factors go into how much we build before we hit our peak and how fast we fall once over that peak. And of course, exercise is a huge factor in this. Weight-bearing activity that forces you to challenge gravity is huge in preserving or even building bone density by breaking down the bone so it can build back even stronger.

Better Sleep

Exercise can improve sleep quality by expelling built-up energy. Another way sleep improves is the cycle of body temperature brought on by exercise. During activity the temperature increases; once activity has stopped the temperature gradually decreases, causing chemicals to be released that promote drowsiness.

Increased Energy and Stamina

In the short term, exercise increases blood flow throughout the body to improve energy. Over time, exercise causes improvements in cardiovascular health, allowing the heart to pump more oxygen-rich blood throughout the body, therefore increasing energy.

Reduced Cholesterol

When exercise, weight loss, and dietary intervention are combined, the LDL (bad) cholesterol levels decrease while HDL (good) cholesterol levels increase.

Decreased Risk of Chronic Diseases

If you’ve ever heard the phrase “exercise is medicine,” it will be no surprise that exercise actually reduces the risk of chronic diseases. Various things happen in the body to cause this, but the most important is that by getting active, the chances of developing Type 2 Diabetes, some cancers, stroke, heart disease, and more are drastically reduced.

Increased Coordination and Balance

By staying active, people learn how to be more coordinated and balanced. Motor control over movements becomes more natural the more it is practiced, and will translate to real-life scenarios. In the long run, especially through aging, this is beneficial to help prevent falls and the negative consequences, such as fractured bones, that come along with them.

The Mental Benefits

The mental benefits of increased activity include the following.

• Stress relief
• Positive mood
• Improved mental alertness
• Reduced anxiety and depression
• Improved self-esteem
• Increased cognitive function

Most of these improvements occur due to the increased blood flow to the brain, which acts on the hypothalamic-pituitary-adrenal (HPA) axis. This area of the brain interacts with several other regions, including the limbic system, hippocampus, and amygdala, which are correlated with motivation, mood, and responses to stress. Other noted improvements may be explained by providing distraction, improving self-efficacy, and increasing social interaction. Research shows that exercise can improve cognitive function by promoting neuroplasticity. By staying active throughout adulthood and senior years, cognitive decline can be prevented.

Although many mechanisms go into this complicated process, one thing that is known is that the rate of neurogenesis, or the production of new neurons, is greatly increased by exercise. This may be the result of increased blood flow to the brain during exercise, with an abundance of oxygen and nutrients.

Other Benefits

A lot of benefits that come from exercise can be measured or researched. Some benefits are harder to measure but still occur. We learn how to set realistic yet challenging goals, learn the discipline needed to accomplish those goals, and learn more about ourselves. We can gain a better understanding of how much we can push ourselves and improve our mind-body connection.

How Much Should You Work Out?

The current Physical Activity Guidelines for Americans outlines the recommended amount of activity for different age groups. Adults should do at least 150 to 300 minutes of moderate-intensity aerobic exercise, or 75 to 150 minutes of vigorous aerobic exercise a week. Most health benefits can start to be seen at the minimum amount; however more benefits are seen beyond 300 minutes of activity a week. Adults should also do some type of resistance-training exercise at least two days of the week.

At NIFS, we have multiple group fitness classes every day to help you reach your goals and hit the minimum requirements. Check out the group fitness schedule for 30–60-minute classes to help you achieve at least 150 minutes of exercise a week.

I celebrated my 40th birthday almost a year ago but postponed writing the “I’m 40 now” blog until now, mainly because it is a bit played out. But more importantly, I wanted to see what this 40 thing was all about before writing about it.

My 40th year on this planet started off great, spending that 18th of August completing 40 holes of golf with the wizard Alex Soller and a few other NIFS characters. It was a very memorable day, one that helped make me feel that 40 truly is just a number and I am still very capable of fitness feats. So I leaped into my 40th year like I have so many previously, with grit and an attitude that nothing will slow me down. I love to move around and I love to challenge myself, and I looked forward to what the year had in store for me.

Do You Really Start to Fall Apart When You Hit 40?

However, Father Time soon showed up with a message that a few adjustments must be considered if I was to continue to stay as active as I like to—nay, need to—be. It was crazy how it seemed so many things were going wrong physically, or it took so much longer to recover, or my drive to train hard lessened. I was reminded of Rocky’s last conversation with Apollo before the Drago fight, where Stallone attempted to talk Apollo out of the fight, stressing that they have changed and were no longer able to do what they used to.

I had always dismissed the messages from men my senior saying, “just you wait; things will change”; but it was becoming more and more apparent that those guys were right. I am not so naive that I would run obstacle course races and hit PRs in the gym left and right and at the level I was used to; I just didn’t expect so many reminders that I am not who I once was physically.

Check Yourself: Five Steps for Adjusting Workouts as You Age

Have you ever heard the saying “Father Time is undefeated”? Sometimes it’s a pretty tough pill to swallow, but here are a few system checks that I have made, which you can use to keep moving as the years keep coming.

• Check your expectations/mindset. Although it can be hard to handle at times (believe me), physical abilities are going to change and it is important to evaluate and adjust your expectations. This will help when you are faced with a physical challenge that you might have formerly handled pretty easily, to determine whether you should attempt it or live to fight another day. Your mindset is your story; now it’s just the next chapter. Negative self-talk about what you used to be able to do will not help in moving forward positively. I have found it helpful to manage the minimums and find that new normal. This will keep you safe both physically and mentally.
• Check your warm-up. Maybe the days of performing a few stretches and jumping jacks and then hitting heavy back squats are gone, and that is okay. Taking a few more minutes to warm up properly, including mobility and core stability drills followed by dynamic stretching exercises, is key in avoiding big-time soreness and injury.
• Check your focus. My focus has changed a little from conquering any fitness challenge I can get my hands on to doing things that would allow me to continue to do things. I am no longer a competitive athlete nor am I all that interested in how much I bench press. What I am most interested in is staying active and being able to move around. Because of that, my focus has shifted a bit and my training has as well to accommodate it. Check your focus to make sure your training is providing what you need. If you are still chasing a strength goal or PR in a half-marathon, go get it, but do it safely. If your focus is like me and you want to be a great mover, fit and healthy, your training should be centered around that. NIFS can help with that!
• Check your workload. I am a staunch supporter of the ACSM’s guidelines for physical activity: getting 150 minutes of moderate-intensity exercise per week and 60 minutes of vigorous-intensity exercise; you pretty much need to move every day for at least 30 minutes. That shouldn’t change, but check your intensity and exercise selection for those training sessions to determine whether the workload matches what you checked from above. Also, you should consider the total time being active for the day and not just your training session. Training hard for 60 minutes followed by 8 hours of sitting can be just as bad as not training at all. Focus on staying active throughout the day by taking the stairs, parking farther away, or playing with the kids when you get home.
• Check your recovery. This has been the most impactful area for me entering my fourth decade: how I am approaching my recovery. I have always been pretty solid with my recovery strategies, but I’ve really had to up my game these past few years. One game changer: ICE! I never really used ice in the past, but now I ice almost every night, especially after a back injury that put me on the couch for a week. Regular massages and other soft-tissue treatments are strategies I highly recommend for recovery. But if I were to put a thumb on what has helped me the most for recovery, I have stopped trying to pack so much into a training session or a day, period. Take time to reflect and relax from the daily stressors, whatever that looks like to you. Enjoy fitness and moving every day, rest and recover properly, and you can keep moving for a lifetime!

As I said before, and it’s worth mentioning again, for me it has been about finding a new normal and managing the minimums. It’s so important that you wrap your mind around what your normal is and what makes you happy. It might not come with blue ribbons anymore, but every day is an event. Go out there and win the day!
