FAITH LAPIDUS: Another study found that regular physical exercise does not harm joints. Scientists from Germany and the United States considered earlier research on the effect of exercise on joints. They did not find a link between normal exercise and knee osteoarthritis.
If you are still worried about exercise for osteoporosis, try taking a walk. The Mayo Clinic says walking helps your bones. However, you have to do it correctly. The Mayo Clinic says hold your head high. Straighten your back and neck as much as possible. Tighten the chest muscles. As you move along, let your shoulders and arms move freely and naturally.
Walking raises the levels of chemicals in the brain known as endorphins. They reduce pain and make you feel happier.
