Jumping—yes, jumping!—may help. Recent study: Postmenopausal women with minor knee osteoarthritis who did high-impact exercise (step aerobics with quick turns and jumps) three times a week had improved stability and stronger knee cartilage than those who didn’t do this exercise. Why: Jumping and other high-impact movements build collagen and bone. Implication: Men and women with knee osteoarthritis may benefit from high-impact exercise but should get an OK from a doctor first.
