Getting fit, healthy and in shape takes a lot of commitment and dedication. And, about one minute of your time. If you can't spare one minute a day for your health then you are not too serious about it.

Think you have no time to get fit? If you have one minute to spare, you do have the time. A single minute of very intense exercise produces health benefits that are similar to longer, traditional endurance training, according to researchers from McMaster University in Hamilton, Ontario.

"This is a very time-efficient workout strategy," says Martin Gibala, a professor of kinesiology at McMaster and lead author of the study. "Brief bursts of intense exercise are remarkably effective." "Most people cite 'lack of time' as the main reason for not being active," says Gibala. "Our study shows that an interval-based approach can be more efficient. You can get health and fitness benefits comparable to the traditional approach, in less time."

And you don't have to be on a stationary bike to reap the benefits. "The basic principles apply to many forms of exercise," he says. "Climbing a few flights of stairs on your lunch hour can provide a quick and effective workout. The health benefits are significant."
