Lanier, I found out yesterday the reason why dad is wanting to stop using the treadmill. He has fallen 3 times while using it. He says he's wearing out the knees of his pants sooner than the soles of his shoes. :-) My dad, although he does know how to swim, he does not have access to a pool. I wonder if there are any pwp who has tried 1 of those new Air Strider machines. Since your feet stay stationary using it, would it be easier for a pwp?
