Got Health?

Moderate exercise seems to be enough to make you healthy — only 30 minutes of walking or similar activities once a day or an hour of walking three times per week.  If you want to become more fit, in contrast, you’ll need to expend a minimum of 2,000 calories a week on some form of continuous, sustained (also called “aerobic”) exercise.
