You are doing speed squats, regular loaded front squats, good mornings, and rack pulls in the same workout?!!! Are you nuts or are you the next Brian Siders?
How on earth can you do so many pressing exercises in one workout and throughout the week?
You have WAY too much spinal loading going on throughout the week and in individual workouts. I predict burnout from this routine in two weeks, IF not from one session.
Dude, do yourself a favor. If you want to follow a Westside template and get bigger, simply follow a Westside template and eat more! There is hardly any use in "altering" it to get bigger. I have followed conjugated periodization, Westside style for a year and half and getting bigger as we speak since I finally realized that my food intake was not high enough. I do not do any more than 4 exercise per workout, including speed exercises. I have been to a Westside seminar and going to a Metal Militia seminar in March and getting heavily involved. So if you have any more questions, go ahead and ask. Again, get strong in a FEW exercises and eat more and you will see the mass come! In my view, volume is overrated to SOME extent!
