Do you have any set of exercises to use with individuals who have osteoporosis (this person also has arthritis and cervical spinal stenosis, and according to her Physical Therapist, should do weight bearing exercises, but keep her spine in neutral position, and not lift anything above her shoulders.
Cervical spinal stenosis can be a serious condition. I agree with all of the previous answers. Perhaps the best recommendation is that you consult with the client’s physical therapist and see if you can bring the individual in as one of your personal training clients. Modest ROM and some loaded exercises can perhaps be helpful, but not in a group exercise setting.
Take care, Daniel
