I was checking out the PHAT routine here. I notice there is no barbell bench press and barbell overhead press given in the sample routine. Only squats, stiff-legged deadlifts, and pendlay/bent over rows. How long did u do PHAT by the way?

PHUL has squats,deadlifts,overhead press,bench press and barbell rows. Upper power day has barbell bench press and barbell overhead press.

For bench press, the sets/reps are 3-4 sets,3-5 reps. For overhead press, it is 2-3 sets,5-8 reps. Is it up to me whether I want to do 3 sets or 4 sets for bench press?
