hi, rose. like you, i am in my 50's. i find that lifting weights to strengthen my back has helped my strength and posture. it makes holding my head up easier. please ask your MD if you are physically up to lifting weights on a weight machine. (do not use free weights.) the weights do not have to be heavy; the purpose is not to become a body builder! the goal is to strengthen your muscles to help the bones do their job. science has shown that lifting weights, even at our age, is good for both muscles and bones! it strengthens both. good luck to you!
