I'm waiting for one more meeting with the doc and insurance approval and then I'm moving forward.
I'm 378 - I joined a YMCA with 2 pools and lots of Water walking classes. I go in the morning - I walkin with my swimsuit on, flip flops and my robe - I don't care what others think I'm there to get my health back. During water walking you just walk up and down the pool and since you are in water it doesn't ahve the impact of walking on hard surfaces.
Before I did the pool I started out stretching in the morning before I got out of bed and again before I went to bed. It was little things that I really helped me get stronger nothing too strenuous.
Good luck and hang in there.
