Thanks, I'll keep in mind it'll be a while before I attain 'squat mastery'. But what I'm afraid of is coming from being able to do ~1.5xBW on the smith machine to full depth, and then having my back and knees explode when I do an actual squat with that load.
I think I might try working up to something I know I can handle easily for one rep, like 185 or 205, on the squat rack on an off day. I read about the whole balance/strength thing so I know I won't be able to do as well with power rack as on smith. But I was wondering how much the difference would be.
