I need to lose over 100 pounds. I can't exercise much right now. I have two fractured feet, bad back and hip. Can only stand about 2-3 minutes. Idea?

Orthopedic inserts. otherwise known as orthotics, sounds like you need more support. Also talk to you primary about vitamin deficiencies. Brittle bones could be a systemic serious issue. Orthotics can provide better distribution of your weight. They are devices that fit in your shoes. They are thin and don't take up much space.
