My back angle for squats and for deads is not the same at all. My back is nearly flat with proper dead set up because I have very long arms and a short torso. I am wider than I am tall. I already posted a power clean form check and they said my set up is good. It's the same set up as deads. But when the bar is in the proper low bar position on my back for squats, my back angle is such that it keeps the bar path at mid-foot.
Additionally, holding the bar in the proper position for LBBS (squeezing the upper back muscles tight) nearly kills me. I'm sure this is part of my problem with keeping my lats engaged and keeping my upper back flat during deads. This is the probably main reason that squatting heavy before the deads is killing my deads. My lower back stays flat and tight. It's my shoulders that fall and my upper back that rounds. My low back doesn't bother me until the days after deads. And the squats aren't helping that, either.
I don't think I'm too vertical in the squat. Think about it. Why do you think my lower back is getting so wrecked by the LBBS? Because I AM training the posterior chain. As much as I would love swole quads, my goal is to be strong in everything, not just quads.Maybe because you are too vertical in the squat (puts less load on the lumbar and leaves posterior chain out of it, which doesn't improve your deadlift magically as it should, just swole quads).
I'll post a vid of my squats. Other than a forward lean on the last rep, I think my bar path is pretty good. I honestly don't see anything majorly wrong with my squats.Don't post DL's then, but post squats?
