A (as the above answer stated)
WHY:
Strength training puts stress on one’s muscles by definition. It requires short bursts of demanding physical tasks. This causes microtears in the muscle, which stimulates the immune system to “heal” these tears by creating more muscle to repair the (harmless) damage and thus increases muscle mass. Weight is lost of course is usually a result of strength training, but muscle gain is a much more noticable result of strength training.
