I actually haven't read that book, only Starting Strength to learn how to lift properly.
Like I said, why don't you try one of these routines now.
I agree I'm not an expert, but I've read enough from those who are to figure it out for myself, and my own results have borne it out. I did stick to the PTC beginner routine until I could bench 120, even as my squat progression slowed down, it's held me in good stead for starting 5/3/1. I don't think I would have been able to do the volume of upper body assistance otherwise.
If there was a GPA affiliate within 400km of me, I would compete - it's mainly thanks to Markos that I stropped training like a typical idiot bro and started the path to getting stronger.
I didn't choose TM for myself as I'm still eating at a deficit, therefore it was not well suited. Given that you're on gear as well you should be able to smash it out.
