(HealthDay News) -- We all know that exercise is good for us, but how much do we need at each stage of life?
The U.S. Library of Medicine suggests:
- Adults should get 30 minutes of aerobic activity each day -- in the form of walking, running, biking or swimming. Additionally, they should practice strengthening exercises -- such as lifting weights or climbing stairs -- twice weekly.
- Children and teens should get 60 minutes of age-appropriate physical activity each day, such as playing at the playground or biking. And three days per week, they should perform muscle-strengthening and bone-strengthening exercises, such as doing push-ups, jumping jacks, playing volleyball or working with resistance bands.
- Seniors, pregnant women and those with disabilities should check with a doctor to develop a personal exercise plan.
