Experts agree that exercise is crucial for good health, especially when it comes to preventing chronic diseases. Movement helps every bodily system function better. So why do so many people find it difficult to make the time to exercise? Our technology has lured many of us into a sedentary lifestyle sitting at a computer.

Dr. Jordan Metzl says it doesn’t have to take a lot of time to get enough exercise to benefit both your body and your mind. Short bursts of intense activity could be just as good as longer, sustained periods of moderate activity. In some case, the high intensity intervals may be even better. He also recommends working non-exercise activity into your day, like taking the stairs or walking the dog.

What Is the Best Exercise?

Dr. Metzl prefers to write personalized exercise prescriptions for his patients. Unquestionably, the best exercise is the one you will do on a regular basis. Consequently, it has to be something that is fun. There’s an added bonus if the activity is social, like a tennis match or a dance class. Knowing that others rely on you to participate can often be the extra nudge needed to help you find the time to exercise.

In addition to fun, many people respond well to simple incentives. One corporation has established a program to reward each employee $1 for every day in which the person walks at least 10,000 steps. Figuring out rewards for good behavior can help all of us work more movement into our lives. It may be best to exercise in the morning before the day begins and other obligations can interfere.

Exercise is not about weight loss, though people who make time to exercise regularly may lose weight. Most importantly, it is about controlling inflammation. Moreover, physical activity, with all its benefits, doesn’t have bad side effects as drugs do.

What About Dancing?

A few studies suggest that dancing is a physical activity with special cognitive benefits. Cohort studies of older people have found that those who regularly participate in ballroom dancing are less likely to develop dementia. Whether this is due to the cognitive challenge or the social aspect of dancing is not clear, but it appears to help the brain in ways that ordinary exercise such as running or swimming do not.
