“… strength training has bone benefits beyond those offered by aerobic weight-bearing exercise. It targets bones of the hips, spine, and wrists, which, along with the ribs, are the sites most likely to fracture. What’s more, resistance workouts—particularly those that include moves emphasizing power and balance—enhance strength and stability. That can boost confidence, encourage you to stay active, and reduce fractures by cutting down on falls.
Numerous studies have shown that strength training can play a role in slowing bone loss, and several show it can even build bone. This is tremendously useful to help offset age-related decline in bone mass. Activities that put stress on bones stimulate extra deposits of calcium and nudge bone-forming cells into action. The tugging and pushing on bone that occur during strength training (and weight-bearing aerobic exercise like walking or running) provide the stress. The result is stronger, denser bones.”
