If you've ever watched kids on a playground, you've seen the three elements of fitness in action when they:
run away from the kid who's "it" (endurance)
cross the monkey bars (strength)
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. Better yet they should enroll them in your martial arts school.
Endurance develops when kids regularly get aerobic activity. During aerobic exercise, the heart beats faster and a person breathes harder. When done regularly and for extended periods of time, aerobic activity strengthens the heart and improves the body's ability to deliver oxygen to all its cells.
Aerobic exercise can be fun for both adults and kids. Aerobic activities include:
Tae Kwon Do
Improving strength doesn't have to mean lifting weights. Instead, kids can do push-ups, stomach crunches, pull-ups, and other exercises to help tone and strengthen muscles. They also improve their strength when they climb, do a handstand, or wrestle. Kick and punch pads.
Stretching exercises help improve flexibility, allowing muscles and joints to bend and move easily through their full range of motion. Kids get chances every day to stretch when they reach for a toy, practice a split, or do a cartwheel.
