Give it a go auger it's is brutal but fun. All the weight/rep schemes are weight should equal failure at that final rep. And with the squats being 20 the weight will be much less then you could imagine.
In my case I did the BHN press with 135 the bench with 185 and the squat 225 for the very first time I tried this I've since adjusted the weights up. The guys that sent me this work out did it EOD for 16 weeks he put on 17 lbs of muscle and added 70 lbs to his squat. I'm doing this for some endurance and of course to see if I can add strength.
