Do you really think it is worth a try, or will it just be a recipe for disaster most likely?
My best squat is 315x5 (that's ATG oly style with belt only). I am not sure what my max single is for squat but it is bound to be horribly weak compared to my deadlift (480 with belt and chalk only - yes it really is that much more than my squat... you really want a laugh you should check out how far my bench is lagging behind them both lol). My squat has been improving quite drastically on and off (a year ago it was a pathetic 225x1 to parallel with questionable form). I seem to get awesome gains for a while then plateau badly. I guess I am just looking for a kickass solution to bring my squat into the 400's quickly. Once it is in that ballpark I will work on bringing my bench up. I am pretty sure I know exactly why my squat and bench are so far behind my deadlift though
I am actually starting a new routine tomorrow - kind of similar to your 3-day powerlifting routine, so I will see how that goes. Maybe I will use the Russian squat program (or something similar) the next time I'm on gear. I figure it's not the kind of thing you want to attempt natty.
