Physical activity helps bones become stronger and thicker, just as a muscle gets stronger and bigger the more you use it. Bones are living tissue. Weight bearing physical activity causes new bone tissue to form, making bones even stronger. It also makes muscles stronger, and muscles push and tug against bones to make them even stronger. Physical activity also makes you better coordinated, which can make you less likely to fall and break a bone
