can you ask your doctor what kind of exercise is safe for you? sometimes hospitals will have classes for people with limitations. also community colleges will sometimes have those types of classes. I have back and neck pain also but I can keep it under control by seeing a chiropractor. it does sometimes make it hard to exercise though. also a good way to start eating healthier is to gradually add more vegetables into your diet if you are not already eating alot of them. I like to keep alot of frozen vegetables in the house, they dont need to be peeled or chopped and it only takes a few minutes to cook them.
