But strength training is not all in vain if one of your goals is weight loss. Therefore by increasing the muscle tissue you have will allow you to burn more calories in the day. This is good because by increasing the amount of calories you burned in a day without increasing food consumption you may begin to see weight loss. All muscle turns to fat if you quit the program. The increase of muscle tissue is not due to increased number of muscle cells.
Muscles cells remain muscle cells where as fat cells remain fat cells.
They only change size. With bigger muscle cells you can lift more weight. But once you stop exercising your muscle fibers become smaller. You never get or loose fat cells, they only increase and decrease in size. Any weight gain after one quits is due to increases in fat storage caused by decrease in caloric needs as lean muscle mass decreases.
