Help! I have a chance to exercise with a trainer for free but my doctor is totally against me doing any kind of exercise. He just wants me to sit at home and sleep. I have COPD, Arthritis, & Idiopathic Hypersomia (Sleep a lot). He is afraid that I will make myself to tired and might have a COPD attack and not be able to live through it. I think he is wrong but what can I do. I need to loose weight for sitting around is what got me up to this obese weight. What can I do? HELP!
