Get Up and Get Moving
Aim for a total of 150 minutes a week of moderate-intensity exercise (brisk walking, ballroom dancing, active yoga, leisurely biking) or 75 minutes a week of vigorous-intensity exercise (jogging, running, tennis, biking, swimming laps). If you’re not currently active, your doctor can help you plan reasonable starting goals, bearing in mind your general health. Keep in mind that even a little bit of daily physical activity, of any intensity, is better than none. And even very short bouts—less than 10 minutes, for instance—count toward your overall goal.
