If you are comparing powerlifting to bodybuilding training, it is quite simple. basically comes down to hypertrophy training vs. strength training. Heavy weights low reps trains muscle and CNS to become stronger. Higher reps (repetition or bodybuilding method) increases muscle size more bc of glycogen, water and other factors. Most idiots in the gym say "higher reps for toning", its actually the opposite..strong muscle=toned muscle=low reps (max effort and dynamic effort training) mass=high reps
its complicated stuff how the body adapts to different training styles, but maybe that helps.
