i always warm up a few mins. before training. i have never used any kind of wraps or wrist supporters. in the past 2 weeks, my elbows hur so bad when i try to straighten them out. when i push the weight it hurts, and kind of heavy pressure hurts. its right on the tip or ball of the elbow. i dont know what the hell is wrong with me but it hurts. sencondly my knees are also starting to hurt when i bend them.... is this some kind of rapidly developing disorder, or am i overtraining, or what. Im getting a little worried here.
