Ben I actually find back squats at the end of the workout to be more effective. Althought the weight being pushed is significantly less all tension is taken by the quads. I find it far easier on my lower back as well.
Ya, lol fuck man, if my legs arent sore the same day i train them i know im in for a rough ride. I used to get DOMS in my legs very bad, to the point i could honestly barely walk, get off the couch or get out of bed normally. This doesnt happen anymore though ever, which is good. I suspect its from better PWO nutrition, because i still do as much in the gym if not more. That PWO protein and carbs then a whole meal within the hour is crucial for speedy recovery. Before id wait a couple hours to eat after my shake now its about 45 mins NEVER longer than an hour.
