This has been a problem that's been plaguing me for some years now. Whenever I start walking at with any kind of intensity my shins just start going on fire and after 10-15 minutes I literally have to use my quads to lift my lower legs like they were dead weight to keep walking.
I know everyone is thinking shin splints but I'm not so sure. I'm a pretty small guy at only 160lbs but this is a problem that's proven to be quite consistent with this weight. On the theory that it was excess bodyfat and weak legs that caused it I had cut down from 155 to like 135 like a year and a half ago ( i know i know ). The problem vanished. I surmised that my legs were probably too weak for the weight of my body. I've since started bulking again for about the last year and boom the problems have started again with the walking I'm doing on campus with the new semester.
Any tips/advice. I'm thinking I may need to train my shins or something but how the hell do you even do that?
