I don't remember the routine from FLEX exactly, being that you wouldn't catch me dead buying an issue of FLEX, I just glanced over it at the newsstand.
However, from what I remember there was quite a bit of machine work, with some very high reps.
From what Batista told me, and from what I saw him do, he does quite a bit more free weights with much lower reps than what FLEX published.
This is in no way indicative of what his "program" is, but what I saw him do at the gym in State College was:
Barbell flat bench
Dumbbell shoulder press
Dumbbell lateral raise
Wide Grip Pulldown
Close-grip bench press
Alternating dumbbell bicep curls
These were all done in the 8-12 rep range for 2-3 sets each. Keep in mind that he had a show to perform that very night, so he didn't train any legs, and I have no idea how his training changes when he has a bit more recovery time before his next contest.
All I know is that he told me he pretty much sticks to the basic movements with free weights most of the time due to the limited time he actually has to weight train, which seems opposite of what FLEX published, for him and for all bodybuilders, it seems.
