Physical activity is considered a Miracle Drug for many different reasons, but one of the main benefits it has is that it strengthens our bones and muscles. This is especially important for children as they grow and develop. Without exercise, their bodies might not develop properly, which can lead to health issues in the present and later on in life.

One of the reasons physical activity is essential for strengthening a child’s bones and muscles is because children’s bones and muscles become stronger when they are forced to bear weight and work against the forces of gravity. This can be accomplished through many types of activities, including playing active sports like tennis, jumping rope, running, dancing, and more.

Think about lifting weights—people aren’t just doing it for fun! Lifting weights puts stress and extra weight on different muscles in your body, which ultimately helps them to become stronger.

Bones and muscles are living tissues that gradually change in response to the weight and force that are placed upon them. This means that both your bones and muscles will adapt to regular physical activity by building more bone and stronger muscle tissue, thus making your body stronger and healthier.

Because children’s bones are not fully developed until late in their teens, regular physical activity will ensure that a child’s bones remain strong and continue to grow properly. One study from the Journal of Bone and Mineral Research reports that the best time for girls and boys to improve their bone strength through physical activity is during prepuberty (around 10-13 years old) and peripuberty (the general time around puberty).

Developing strong bones and muscles in childhood also reduces the risk of injuries—like fractures, tears, and sprains—later on in life. Additionally, continued physical exercise is essential to maintaining healthy bones and muscles throughout the rest of your life, as a lack of activity can lead to adverse conditions like osteoporosis.
