my lower back is getting fatigued from a couple of weeks. The fatigue came from squats, but now it never goes away. I can't stand, even for a short time without feeling fatigue. It has not recoverd even in 2 days of total rest. I think i'll have to take a week off and stop the cycle 2 weeks earlier. has this happened to everyone else? i mean it is not a pain from an injury it is like you're waorking it out constaltly, evem if you're just walking.
