Is Exercise overrated? An interesting question coming from a personal trainer with 26 years’ experience! Exercise and activity are essential components toward achieving good health. It is one of the 6 aspects of lifestyle medicine and can extend your life and help prevent disease. It can also help your state of mental health substantially. Knowing all this, is it possible that we over-emphasize exercise at the expense of other aspects of health? Do we isolate exercise as something done in a formal manner? Have we have forgotten the incredible value of working activity into our daily lives?
What is exercise?
Exercise includes three different facets: aerobics, resistance training, and flexibility training.
Aerobic exercise is any mode of exercise that raises your pulse to between 60% and 90% of your resting pulse. Common modes of aerobics are walking, running, biking, rowing, jump roping, and swimming.
Resistance training is for building and maintaining muscle mass. You can lift weights, use your own body for resistance, like pushups and sit-ups, or do isometric exercises.
For flexibility, static held stretches or modalities like yoga are all good to bring better range of motion. One should choose a modality that he or she enjoys.
One of the great things about exercise is that there are many different ways for you to achieve good results.
What are the benefits?
The benefits of exercise are too numerous to list in this article. The Harvard School of Medicine lists these top benefits:
Blood pressure: Exercise may lower blood pressure if done on a regular basis.
Anxiety and depression: Exercise appears to ease anxiety symptoms right away, and over the long term. Many studies have shown that effective physical activity can reduce the risk of depression and treat depression itself.
Insulin sensitivity and diabetes: Activity can improve your body’s response to insulin, the hormone that helps control blood sugar levels. Better insulin sensitivity may lower the risk of type 2 diabetes.
Sleep: Getting more physical activity may improve your sleep efficiency, and help you sleep more deeply.
Weight Loss: Exercise is NOT the main ingredient to substantial weight loss. Still, exercise may help stave off the weight gain that often occurs as people age. To lose weight, you’ll eat fewer calories. If you do lose weight, being active helps prevent weight regain. Even without weight loss, you still reap the benefits of exercise.
Analyses of the data involving exercise shows that by engaging in moderate exercise, 150 minutes weekly, one can lower risks of chronic diseases by up to 35%. But with all this said, most people don’t want to engage in formal exercise. It is time consuming and can cost money, and not everyone looks forward to a sweaty experience. Is there another way?
Activity
If exercise isn’t for you, then let’s do something really NEAT–Non-exercise Activity Thermogenesis. NEAT encompasses the calories burned while living life—walking to work, typing, folding clothes, washing dishes, running errands and so on. Sleeping, eating, and formal exercise are not included.
Research suggests that prolonged sitting can be as bad for health as smoking (Owen et al. 2010). Sitting “deactivates” the brain and lowers metabolism. Limited physical activity, low levels of mental stimulation, and too much time on screens and mobile devices have a detrimental effect on the brain over time (Nussbaum 2006). Movement is crucial, but you don’t have to run a marathon.
According to the Centers for Disease Control, prolonged sitting is a significant contributor to chronic diseases. When people get up and move, they’re likely to see big benefits:
- 21%–25% reduction in risk for certain cancers
- 20%–27% reduction in risk for stroke
- 27% reduction in risk for diabetes
Consistent exercise can help to counteract the effects of sitting too much. When that becomes difficult or inconsistent, fitting in more activity, within what we are doing daily, becomes a viable and valuable option.
Also good for your brain
The simple activities of NEAT can build and strengthen the brain. Dr. John Medina refers to physical activity as “cognitive candy.” The two primary foods for the brain are oxygen and glucose. By moving we increase the flow of oxygenated blood and glucose to the brain. Proper glucose levels are associated with stronger memory and cognitive function.
When a person sits for longer than 10 minutes, the brain downshifts and it becomes more difficult to pay attention (Jensen 2000). Office settings and school environments typically require doing a great deal of work in a seated position, and yet the brain is least productive when sitting (Eckmann 2013).
One big advantage of concentrating on an active life has to do with immune system health. However, people who engage in steady, intense exercise, without proper recovery, can compromise their immune systems. Marathon runners are high risk for the common cold and mononucleosis for 30 days after each marathon they run. Body builders have much shorter life expectancy. So, if you are exercising, don’t overdo it.
Exercise can’t undo a poor diet
You can’t out exercise poor eating. We have all fallen victim to thinking that we can take certain liberties and eat unhealthy foods because we exercise. This is a terrible mistake. Food and diet are still king when it comes to health. You’ll never burn off the calories you eat from fatty-foods, and it won’t clear your coronary arteries of plaque buildup from eating too much cholesterol and saturated fats.
Would you like to fend off all chronic disease? Possible by lowering your risk by as much as 80%? This may all be possible with a lifestyle that includes, activity/formal exercise, a plant-predominant diet, a good night’s sleep, abstention from smoking and substance abuse, and managing your stress.
Exercise is great and valuable. But it isn’t a stand-alone and it won’t undo other poor lifestyle habits. Including exercise and activity as part of your healthy living will “add hours to your day, days to your year and years to your life.”
