In a study of men in their 60s and 70s, those who routinely did 30 minutes of exercise six days a week had a 40 percent lower risk of dying over a 12-year period than men who were sedentary.
It’s interesting to note that exercise was so beneficial among the men in the study that its effects were on a par with those of quitting smoking.
Additionally, another study (and this one applies to all age groups) found that if your goal is to lose weight, exercising for more than 30 minutes might be a wasted effort. In the study, participants who exercised for 30 minutes a day for three months lost just as much weight and body fat as those who exercised for an hour a day for the same period.
This difference in weight loss was seen despite the fact that the 60-minute group burned twice as many calories, on average, as the 30-minute group. It’s possible that those who were assigned to the 30-minute exercise group saw their training as more doable and therefore had the desire and energy for more physical activity afterward; and those who exercised for 60 minutes probably ate more.
ForMen takeaway: Exercising is good for you. Even if you don’t have a lot of time, 30 minutes might be just enough to do the trick.
