I am an older, overweight, arthritic woman and I just got this to help me with my issues. The first time I used it I felt absolutely rejuvenated internally. I admit I have a motivation problem but with this I can shame myself into at least standing on it for ten minutes. It seemed to be helping with my arthritis pain. I have a knee replacement but other leg my knee and even worse my hip of other leg has issues. I started doing some knee rehab exercises and yoga poses then got on U Tube checking out routines there. I did one yesterday that was for seniors and was done from a sitting position. Thought would be real good for my hips but has made it hurt more. I think the knee angle was not good. Should I just back off a bit? any routine reccomendations? I'm not real good with social media but will try to find some info there. That would be an improvement I would suggest. I do not like having to go on my computer for info, etc. Thanks for any help and I am real excited about this.
