HIIT, circuit training, marathons, spin class, on and on, we hear a veritable menu of choices on our fitness quest. Which one is best? What do we do when we keep hearing conflicting stories about the best choices. Long workouts or short? There is no other animal in the wild that willingly consistently runs for hours and hours. I have even heard this puts stress on the heart.

According to studies, the most important thing we can do, is not, do nothing. We have to walk at least 30 minutes a day. We have to move! And sitting, sitting is going to become like cigarettes. Our bodies weren't designed to sit at a desk hunched over a computer all day long. 

Check out the post I did about the HOVR. This incredible device is designed for making you move while sitting at your desk and can offer low-intensity exercise plus burn calories.

The Right Dose Of Exercise For A Long Life

Exercise has had a Goldilocks problem, with experts debating just how much exercise is too little, too much or just the right amount to improve health and longevity. Two new, impressively large-scale studies provide some clarity, suggesting that the ideal dose of exercise for a long life is a bit more than many of us currently believe we should get, but less than many of us might expect. The studies also found that prolonged or intense exercise is unlikely to be harmful and could add years to people’s lives.

No one doubts, of course, that any amount of exercise is better than none. Like medicine, exercise is known to reduce risks for many diseases and premature death.

But unlike medicine, exercise does not come with dosing instructions. The current broad guidelines from governmental and health organizations call for 150 minutes of moderate exercise per week to build and maintain health and fitness.

But whether that amount of exercise represents the least amount that someone should do — the minimum recommended dose — or the ideal amount has not been certain.

 Scientists also have not known whether there is a safe upper limit on exercise, beyond which its effects become potentially dangerous; and whether some intensities of exercise are more effective than others at prolonging lives.

So the new studies, both of which were published last week in JAMA Internal Medicine, helpfully tackle those questions.
