I am starting Pulmonary Rehabilitation next week after a delay of several months because of illnesses and various operations. My doctors have finally signed me off to start it but I must admit to wondering a bit if it is safe for me to do. I am about 5 stone overweight and I haven’t exercised for years. I should really have asked the doctors at the time but for some reason I didn’t think of it. To go or not to go, that is the question. Have any puddin’s out there done PR?
