I will say this again
Mentzer arms looked best when he trained the 3 times a week ala. 1976
Can you say it one more time?
Mentzer first trained his whole body each training day three days a week. He won the Weider version of Mr. America training that way. From there he used a split. Workout A was thighs, chest and triceps. Workout B was back, delts and biceps. He trained four days a week on this split. Then under the influence of Mr. Florida Frank Calta he used a rotation for recuperation split. He used the same A-B split. Except it looked something like this. Monday A, Tuesday off, Wednesday B, Thursday off, and Friday was A. Next week he reversed it where Monday was now B, Tuesday off, Wednesday was now A, Thursday off, and Friday was now B. To throw a monkey wrench in this he didn't use days of the week but maintained three workouts with the rotation a week. He did train with the A-B split rotation for the 1980 Olympia. The crazy routines he came up with after he stopped training was nothing he ever used to compete with.
