Exercise

Motion is lotion for your knees. Strengthening the front and back muscles (quadriceps and hamstrings, respectively) of the thighs can help prevent knee trouble especially in women, who are five to seven times more likely to suffer a torn anterior cruciate ligament (ACL), which is among the most serious knee problems. One way to reduce your risk of such an injury is to practice jumping and landing on a slightly bent knee. Aim to strength-train your legs two to three times a week to build and keep from losing muscle mass.
