I believe you have to find out what your body reponds best to. I spent most of my life training heavy pyramid style but for the past 3 years i've been focusing on volume training and my strength has grown to scary levels. I can't believe how strong i have become somedays.
I often don't even count reps. I push until i get that "feeling" and then i push a little more.
100 reps leg press
20 - 30 rep deads
50 rep leg ext
25 rep shoulder press
