I am 71 and my wife is 62 and we both use the Body Ball daily. One piece of advice: it is easy to overinflate the ball using the pump and measuring strap. Be sure the strap is on the "equator" of the ball so it does not get larger than intended. I am recovering from spinal stenosis and sciatica - my physical therapist recommended a ball to help strenthen my core muscles. It does the trick without fear of "ripping something loose".
