I was about to say that too.... he did decently heavy in his chest workout before going to shoulders.....
Cool, you saw the whole video too? Was pretty good hey? As I recall he started off the chest workout with flat dumbell presses, repping out with 160's, did a bunch of other exercises and at the VERY END of his chest workout he did incline barbell press with 3 plates after being quite exhausted. Then was on to those shoulder presses in the video above.
He also pyramided up to 255 lbs on cambered bar curls, 585 lb deadlifts, 9 plate deep hack squats, and 10 plate t-bar rows to mention a few.
Yet they think he can't bench press more than 225 lbs for 15 reps
