The body: listener question

What about exercise and healthy eating?My body functions well when I eat well. It feels less sluggish, less bloated, it digests food better and I feel energised. However, it has physical injury. When I don’t exercise and strengthen my muscles, the pain is significant. I have also noticed that as a result of these 2 things my body looks different to the periods I don’t.If I am honest, part of the reason I like the exercise  is to maintain this body shape, because I like it. Which I think is part of the identified self, is that right?However, when I stop exercising for a while the injury pain always motivates me back to it.I have often questioned myself this “double benefit” and not really come up with an answer other than that I’m not loving myself if I want to change my body. But I am also strengthening it because it becomes pain free? Now, with your teachings there could be some help! Is Looking into the reason I want a particular shaped body where I should start? Should I stop admiring my body? What is the relationship with a fit and healthy body all about?Thank you!
