D. They promote better bone health

Explanation:

Leg Presses,  Medicine Ball Squat Throws,  Squat Jumps,  & Barbell Curls are all some examples of power activities.

By stressing your bones (when working out), strength training can increase bone density. When you exercise regularly, your bone adapts by building more bone and becoming denser. This increased improvement in bone requires good nutrition, including calcium and Vitamin D. Another benefit of a power exercise is that it improves balance and coordination altogether.
