What is over-training and how can it negatively affect my progress?
« Over-training comes from working out a muscle group too frequently and therefore not allowing the muscle group time to recover. Improper nutrition and lack of sleep can also play a chief role in this. Remember, the muscle grows during the recovery process, not in the gym. Therefore, if you do not allow the muscle time to recover, you negatively affect muscle growth. Symptoms of over-training include fatigue, headaches, lowered immune function, depression, decreased appetite, etc.
