For most lifters, training a muscle group twice per week captures nearly all the available frequency benefit — about 1.5x the hypertrophy results of a once-weekly session — without the recovery overhead of splitting volume across three, four, or five sessions. Beyond twice, the differences become so small that only well-trained athletes with years of consistent training can reliably notice them.
