The government’s latest physical activity guidelines recommend:
- Keep track by the week. Adults need at least 2½ hours of moderate-intensity activity each week, such as brisk walking, or 1¼ hours of a vigorous-intensity activity, such as jogging or swimming laps, or a combination of the two types. These activities should be done in at least 10-minute bouts and can be spread throughout the week.
- Get more ambitious.For even more health benefits, engage in 5 hours of moderate-intensity physical activity each week or 2½ hours of vigorous activity.
- Strengthen those muscles.Adults should do muscle-strengthening activities at a moderate- or high-intensity level for all major muscle groups two or more days a week, including exercises for the chest, back, shoulders, upper legs, hips, abdomen and lower legs. The exercises can be done with free weights or machines, resistance bands, calisthenics that use body weight for resistance (push-ups, pull-ups and sit-ups, for instance) or carrying heavy loads or doing heavy gardening such as digging or hoeing.
- Don’t use age as an excuse. Older Americans should follow the guidelines recommended for other adults if they are able. If not, they should try to be as active as their physical condition allows. Those who are at risk of falling should do exercises that improve balance.
- Kids can make it fun. Children and adolescents should engage in an hour or more of moderate-intensity to vigorous aerobic physical activity each day. That should include vigorous activity at least three days a week, and it should involve bone-strengthening activities such as running, jumping rope, skipping and hopscotch, and muscle-strengthening activities such as tug of war, modified sit-ups and push-ups.
