I have severe arthritis in both knees & back, I can’t exercise like normal people that can jump around & walk & run. I have to use a walker or wheel chair, when I walk I can walk for just a few steps & have to sit down again the pain is so bad. I take celebrex for it every day. I heard pools are a good way to get exercise but there its out of the question as I am on a limited budget & the pool fees cost way too much, any suggestions on how I can exercise every day & try to keep fit like I used to be? I would appriciate any suggestions.
