Important to know

Do Exercise Shortcuts Work?

Clearly any amount of exercise is better than none. In terms of health benefits and longevity, the intensity and duration of exercise do matter. Minimal physical activity does not improve longevity, although it does improve muscle tone and probably has some health benefits.
People who engage in moderately intense exercise that burns an extra 2,000 calories per week live an average of 2 years longer than comparable people who are sedentary. Even at high intensity, you can't burn much more than 15 calories per minute. Ninety minutes per week would only get you to 1,500 calories burned, but this still will be enough to keep off some pounds, decrease blood pressure, lower risk of diabetes and likely add high-quality time to your life.
