When most adults think about exercise, they imagine working out in the gym on a treadmill or lifting weights.

But for kids, exercise means playing and being physically active. Kids exercise when they have gym class at school, during recess, at dance class or soccer practice, while riding bikes, or when playing tag.

The Many Benefits of Exercise
Everyone can benefit from regular exercise. Kids who are active will:

have stronger muscles and bones
have a leaner body because exercise helps control body fat
be less likely to become overweight
decrease the risk of developing type 2 diabetes
possibly lower blood pressure and blood cholesterol levels
have a better outlook on life
Besides enjoying the health benefits of regular exercise, kids who are physically fit sleep better and are better able to handle physical and emotional challenges — from running to catch a bus to studying for a test.

The Three Elements of Fitness
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.

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 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. Examples of aerobic activities include:

inline skating
Improving strength doesn’t have to mean lifting weights. Although some kids benefit from weightlifting, it should be done under the supervision of an experienced adult who works with them.

But most kids don’t need a formal weight-training program to be strong. Push-ups, stomach crunches, pull-ups, and other exercises help tone and strengthen muscles. Kids also incorporate strength activities in their play when they climb, do a handstand, or wrestle.

Stretching exercises help improve flexibility, allowing muscles and joints to bend and move easily through their full range of motion. Kids look for opportunities every day to stretch when they try to get a toy just out of reach, practice a split, or do a cartwheel.
