HARD AND FAST

A New York Times article says scientists have worked out the minimum amount of exercise you can get away with in order to get fit. They key, they say is to do your workout hard and fast.

If your willing to work really hard when you exercise, you may not need to do as much as you think! This comes as good new for people like me who just do not have the time to commit to a daily routine, in particular in winter. The rest of the year, it seems that walking to and from work balances things out.

Researchers at McMaster University have designed  a high-intensity interval training program that involves one minute of strenuous effort, at about 90 percent of a person's maximum heart rate, followed by one minute of easy recovery. Their version sees that process repeated ten times, meaning a total exercise times of 20 minutes, and is supposed to be carried out just twice a week.

The results of the training program, published in a recent review of HIIT-related research, were especially remarkable in the cardiac patients. They showed “significant improvements” in the functioning of their blood vessels and heart.

If time constraints are  keeping you form getting fit, this program may be the one for you. It’s very potent exercise,” says Dr. Martin Gibala, a professor of kinesiology at McMaster  said. “And then, very quickly, it’s done.”

So much for a little and often!
