Muscle does not weigh more than fat, any more than lead weighs more than feathers. A pound is a pound is a pound. Where the misunderstanding often comes in is that muscle is much more dense than fat, so that, by volume, it seems to weigh more. That is, a pound of muscle occupies less space than a pound of fat. In addition, because a pound of muscle burns more fat than a pound of fat, even at rest, by increasing your lean muscle tissue mass, you're helping your body burn more calories. But back to your question.
When you exercise and isolate a muscle group, lactic acid, produced naturally by your body, begins to build around that muscle. As the lactic acid surround the muscle, it results in a burning sensation. While the burn is often associated with becoming stronger, the feeling of heat and fatigue often ends your workout.After a certain number of repetitions, the lactic acid causes muscle fatigue as it interacts in the calcium in your body.This is evidenced by your inability to complete any more repetitions.hile the burn is often associated with becoming stronger, the feeling of heat and fatigue often ends your workout.
