Yes I a doing deadlifts in my back day. Love those to. Any exercise I get to put a massive amount of weight on I love.

I am doing the HIT style training outlined by Mike Mentzer in his book Heavy Duty. I only do one working set of squats but I do 2 warm up sets prior with one set light and the next heavy. I pretty much go to failure when doing the squats. If it feels like I am not going to be able to do the next rep do to the rep I just did then I stop. Right now I am going for strength and mass. I can shred later. Need more mass and I really love to eat.
