The Body Refining Cultivation Method Rein had named the Hercules Art had enormous flaws.
The further one progressed, the more muscles one could control, and the more Gene Source Power was needed to nourish and stimulate every muscle fiber.
Moreover, as everyone knew, muscles would atrophy without continuous external stimulation, and muscle strength and endurance would decline as well. That was the most important reason athletes needed extensive training to maintain their physical condition.
