Women's Weight Training Myth #4 - If you stop weight training your muscles turn into fat.
This is like saying that gold can turn into brass. Muscle and fat are two totally different types of tissue. What happens many times is that when people decide to go off their weight training programs they start losing muscle due to inactivity (use it or lose it) and they also usually drop the diet as well. Therefore bad eating habits combined with the fact that their metabolism is lower due to inactivity, and lower degrees of muscle mass, give the impression that the subject’s muscle is being turned into fat while in reality what is happening is that muscle is being lost and fat is being accumulated.
