Instead of resting a muscle group for days between sessions, the coach hits the same muscle twice a day by changing rep schemes, angles, and time under tension. After the morning session fatigues the primary motor units, roughly 30% of the tissue remains trainable — so the evening session exploits a different fiber population. By day two or three, the entire muscle group has been thoroughly dismantled, then rebuilt on rest.
