What is the effect of exercise on bones?

Explanation:
Mechanical loading from exercise signals bones to remodel and become stronger. Weight-bearing and resistance activities create tiny stresses that prompt bone formation and lessen bone loss, leading to higher bone mineral density over time. This is why the best statement is that exercise reduces bone mass loss and increases bone mineral density. It also helps maintain or increase muscle mass, so saying it reduces muscle mass or has no effect on bone health wouldn’t be accurate.
