I don't know how your surgery/back problems relate to mine but I'm going to assume that they are somewhat similar. I had trouble training, walking, sitting, sleeping... living. I had severe nerve impingement, sciatic pain and massive leg pain on both sides all the way down to the foot. However, it did give me a good excuse to fly first class...I just told me wife I needed more room. More room for free alcohol.
Are you saying you don't need to get slapped in the face before every set?
Listen, this is what I learned. When I was at the University of Arizona and Rob Waldrop, who was the Outland Trophy Winner (awarded to the best college football interior lineman), was squatting. This guy was insanely strong. That day he was squatting in the mid-600's for 7 or 8 reps, and he was just getting under the bar when some kid yells, "C'mon Rob, lets go man!"
Rob just stopped...
