I am wondering if anyone can help me on this or has this problem too. First problem is right now I have a bone tumor on the inside of my left knee *non dominant* so its lost lots of strength cause of it messing up things and then its not dominant either so its less strong cause of that, and im probably going to NEED surgery on it, going to need PT after -_- So its going to be not good for a while. But when I do get back to riding how can I really go and build up strength into that knee or something? Cause I know PT alone wont cut it. Then my second problem I guess is my posture... its B A D! People tell me I walk really hunched over and sitting its really bad too, I always am hunched over. Even riding when not having my mind on it ill start to hunch over, I don't really know how to go and keep better posture. I don't ride much either, its been really on and off so riding doesnt help me in just making me keep good posture and over time making it automatic to be like it all the time. So if you can help I really need some advice!
