6 Minute Workout?

Could this be true? I need to be fit now more than ever so I sure hope pans out.

From the New York Times...

Could it be that most of us are spending more time than we need to trying to get fit?

The answer, a growing number of these sports scientists believe, may be yes.

Six minutes or so a week of hard exercise (plus the time spent warming up, cooling down, and resting between the bouts of intense work) has proven to be as good as multiple hours of working out for achieving fitness. The short, intense workouts aided in weight loss, too, although Gibala hadn’t been studying that effect. “The rate of energy expenditure remains higher longer into recovery” after brief, high-intensity exercise than after longer, easier workouts, Gibala says. Other researchers have found that similar, intense, brief sessions of exercise improve cardiac health, even among people with heart disease.

There’s a catch, though. Those six minutes, if they’re to be effective, must hurt. “We describe it as an ‘all-out’ effort,” Gibala says. You’ll be straying “well out of your comfort zone.”
