My mom is 85 and all she does is sit in a wheelchair. She is losing all of her muscles. She gets physical therapy, but she doesn't do the exercise after that. We meet with the nursing home and they say if she doesn't start moving, she will get blood clots, won't be able to stand, get pneumonia. It is very said watching her waste away. When I exercise, I feel so much better. She says that she doesn't feel better when she exercise. What happens to the elderly when they exercise? Does it just make them tired? Do they not build strength or muscles?
