A March 30th CNN story makes a good point about two recent studies offering contradictory views on the best way to exercise. Whether subscribing to one theory or the other, experts say the overriding message should be that it’s best to move around regularly.
You’ll be healthier, less likely to become overweight or obese and develop consequent diseases.

The studies pit short, intense bursts of exercise versus classic endurance training. Each holds advantages and disadvantages. Researchers at Canada’s McMaster University found that high-speed, interval training for 20 minutes may offer comparable benefits to endurance exercise. The researchers asked seven men to follow a pattern: one minute of pedaling a stationary bike at maximum effort with one minute of rest. The workout addressed one of the main impediments to exercising: that it’s too time-consuming. But the McMaster scientists acknowledged that high intensity exercise isn’t to everyone’s liking. “It’s uncomfortable exercise,…it hurts,” said Martin Gibala, who headed the study. So other people may prefer a Brigham and Women’s Hospital/Harvard Medical School finding that women who exercised one hour daily were more likely to maintain their weight. The study, published in the Journal of the American Medical Association, looked at more than 34,000 women’s exercise patterns over 13 years.

Of course, you could always follow a path between the two approaches. Department of Health and Human Resources guidelines recommend two-and-a-half hours of moderate exercise per week for adults and one hour daily for children and teens.
