Isolation exercises aren't neglected. He still includes curls, shrugs, calf raises, and triceps extension variations, but they're considered secondary to bigger movements like cleans, rows, squats, and pull-ups.
As for training days, while he's very big on recovery methods, most of his programs have three or four training days per week, and he does recommend active recovery training sessions.
Just for squirts and giggles, here's the first workout of Maximum Mass 2, designed for more advanced lifters. (On the off chance Jason sees this, hope he doesn't mind my sharing).
A1) Clean and press 2x5-8
A2) Chin-up 1x5-8
B1) Incline dumbbell press 2x5-8
B2) Bent barbell row 1x8-10
C) Face pull 2x8-10
D1) Lying triceps extension 2x8-10
D2) Hammer curl 1x8-10
There are three more workouts in the week: another for chest/back/shoulders/arms and two for lower body/abs/neck.
P.S. - Your name/avatar freakin' rock. Kudos to you, good sir.
