My dr suggested 2 lbs on each hip(not on chest) sorry, 2 lbs on each ankles and 2 lbs on each wrist while walking. I use my weight in my. home. OMG after I remove them at night I feel as if I could float. Just my own experience. Weight has to be evenly distributed according to my exercise dr. I am baffled by the weights on chest? Investigate. If possible dr also explain a small trampoline is excellent also while watching tv with bars for safety and support, Good luck, Also consider Vit D and K
