Our neighbour text my wife and mentioned that she had one of these and would be happy if it could help me. I think if I can get on and hold something in front of me it might work. Any thoughts or experience on the benefits of using this? My core is weak but actually does work, of course sitting in a wheelchair all day does nothing to improve it. Could using this make a big difference?
