Exercise is important for managing osteoporosis, but some exercises can put stress on the spine and increase the risk of fractures. For example, sit-ups, golf, and tennis, which involve twisting or bending at the waist, and activities with too much running, jumping, or a high risk of falling should be avoided. Experts recommend weight-bearing aerobic exercises like stair climbing and strength training to help increase bone density and decrease the risk of fractures. However, if you already have osteoporosis, certain activities may increase your risk of fractures, so it’s best to consult your doctor before starting them.
