Bones are living tissue. Weight-bearing physical activity causes new bone tissue to form, which makes bones stronger. This kind of physical activity also makes muscles stronger. When muscles push and tug against bones during physical activity, bones and muscles become stronger.
Weight-bearing activities are those that keep you active and on your feet so that your legs carry your body weight, including:
-
Walking
-
Running
-
Dancing
-
Climbing stairs
-
Jumping rope
Playing team sports, such as basketball, soccer, and volleyball. Older teenagers can build even more bone strength through weight training, but they should check with a health care provider before starting any type of training. Some activities, such as swimming, do not provide weight-bearing benefits. But these activities are still good for cardiovascular fitness and overall good health.
