Does Exercise Build Bones? Being physically inactive is a strong risk factor for osteoporosis, and exercise is recommended to help strengthen bones and the muscles that support them. You may also have heard that exercise actually builds bones, even if you have bone loss. Can exercise really do all that?

Exercise can indeed strengthen bones — the problem is that it does this more slowly than many people with osteoporosis need, so you cannot rely on exercise alone. But your bones definitely need weight-bearing exercise and resistance exercise to become stronger. For people with bone loss, other benefits of exercise include better balance, flexibility, and increased strength — all of which can help you avoid falling.
