Use a rope for this hybrid movement, which is part upright row, part face-pull. Do 5 sets of 20 reps and rest 3 minutes between sets.
Instead of standing upright, lean back a bit and use the weight stack as a counter balance. With the rope at the lowest point on the pulley, you'll then pull up to your face and chin area as you pull your hands apart. The entire shoulder complex is going to get hit here.
I'm going to describe a little 6-week program that I call Tsunami Training (I'll get to why I call it that a little later). It's based, for the most part, on training methodologies that I picked up from Ian King and Charles Poliquin, with some razzle-dazzle thrown in by myself.
I'm normally somewhat of a bookworm and science geek, although – to blow a little sunshine up my own butt – I have to say, I'm getting better at reading people.
