Three Important element of Fitness

If you've ever watched kids on a playground, you've seen the three elements of fitness in action when they:

1. run away from the kid who's "it" (endurance)
2. cross the monkey bars (strength)
3. bend down to tie their shoes (flexibility)

Parents should encourage their kids to do a variety of activities so that they can work on all three elements.

Endurance is developed when kids regularly engage in aerobic activity. During aerobic exercise, the heart beats faster and a person breathes harder. When done regularly and for continuous periods of time, aerobic activity strengthens the heart and improves the body's ability to deliver oxygen to all its cells.
