There are certain tell-tale signs that you are working out too hard. You just have to look for them and then adjust your training routine, before they take their toll. You are probably overtraining if you suffer: Sore joints If you do a new routine that works muscles that you are not used to being worked, then you expect to be a little sore the next day. No pain, no gain right? However if you have such soreness that it interferes with your normal daily routine, then you might have tried to do too much too soon. For example if you were working your biceps and the next day you have pain in your elbow, you either tried to lift too much weight or were lifting it wrong.
