Are you overtraining? Below you will find an article to check for symptoms. Exercise is a negative stress on the body, you reap the benefits when you allow the body to recover. In the recovery process the body is adapting to what you have done to it. It learns to optimize oxygen consumption, strengthens bones and muscles and best of all uses energy, hopefully excess fat, to fuel this adaptation. But if you keep exercising while not allowing the recovery process to occur, overtraining can be the result.
