Children and adolescents
60 minutes a day, mostly aerobic and also including muscle-strengthening exercises like gymnastics or pushups; and bone-strengthening exercises like jumping rope or running, included in that hour three times a week
Adults
150 minutes of moderate-intensity aerobic activity, like brisk walking, every week and muscle-strengthening activities on two or more days a week that work all major muscle groups (legs, hips, back, abdomen, chest, shoulders, and arms). Sounds like a lot? Breaking it up in 10 minute spurts is fine. Try this: Go for a 10-minute brisk walk, three times a day for five days a week. You will reach your 150 minute goal.
Or 75 minutes of vigorous-intensity aerobic activity weekly – like jogging or running.
Seniors
If you’re 65 years of age or older, are generally fit, with no limiting health conditions you can follow the guidelines listed above for adults.
