Article that I pulled off the AP:
Excerpts:
_Children’s daily hour should consist of mostly moderate or vigorous
aerobic activity, such as skateboarding, bike riding, soccer, simple running.
_Three times a week, children and teens must include muscle-strengthening
activities — sit-ups, tug-of-war — and bone-strengthening activities such as
jumping rope or skipping.
_Adults should do muscle-strengthening activities — push-ups, weight
training, carrying heavy loads or heavy gardening — at least two days a week.
_Older adults who are still physically able to follow the guidelines should do
so, with an emphasis on activities that maintain or improve balance.
