Do you plan to stand and walk? If so, you need to include weight-bearing exercises in your daily routine. If you plan to jog or run sometimes, then you need to work up to that in your several times weekly routine.
You can help prevent osteoporosis by doing the highest level of weight-bearing exercises you can currently manage. You can treat osteoporosis by including minimal impact exercises and working up to at least low impact exercises.
CVMS Physical Therapy can help you find your starting level and gradually guide you to a higher level Home Exercise Program.
