I've been doing alot of mountaindog workouts, just rotating through the workout of the months from his site for now before I start one of his full programs. Especially the way he lays everything out and the order of the different exercises, these are very effective... I had done one workout the other day it was 6 working supersets of rack pulls for 5 and wide grip pull ups for 6. Another one was one massive clusterset with a weight you can do for 5. Do 15 singles worth ten seconds rest in between each rep. Nasty stuff.
