vigorexia

Also known as over-training, overtraining syndrome

Overtraining occurs when a person exceeds their body's ability to recover from strenuous exercise. Overtraining can be described as a point at which a person may have a decrease in performance or plateau as a result of failure to perform at a certain level or training-load consistently; a load which exceeds their recovery capacity. People who are overtrained cease making progress, and can even begin to lose strength and fitness. Overtraining is also known as chronic fatigue, burnout, and overstress in athletes.
