aerobic

Aerobic exercise is exercise in which you are continuously moving a large muscle group such as in your arms legs and hips for a period of time. Your heart rate gets faster and your breathing becomes deeper and faster.
All adults should get 2 1/2 hours of aerobic exercise spread out over a week, but should be done for at least 10 minutes at a time.
If you have not been active, start slowly and build up over weeks or even months. Walking can be a good exercise to start with.
Every week increase the time you spend with the activity, do it more often or add a second activity. You can increase the speed of your activity or the difficulty of the activity, such as going up hills.
