my default squat is low-bar but quad-heavy. not much hamstrings.
It's probably similar to mine's... but a high bar squat feels SO much more different to me than a low bar squat. So much more "leg" involvement if you will... I consider "leg" when I feel the quads fire well.
With the low bar squat I feel like I'm neglecting my quads just because the posterior chain has been overblown so much on the internet lately: low bar squat for the PC, RDLs for the PC, leg curls for the PC, glute ham raises for the PC, hip thrusts for the PC, reverse hypers for the PC, deadlifts for the PC... OK OK... but what about stuff for the QUADS? What about that?
I mean I would be fine with all the posterior chain work in the world if I knew I had a 2x+ high bar squat and that my quads were strong enough to amortizate any kind of plant or landing... but even when I play ball, I'm scared to penetrate because I know I would be able to pass my defender but I wouldn't be able to stop or control the plant or landing that would follow that penetration.
So I'm limited to just be a passer etc. That can't happen. You can't pretend to squat 160 kg low bar and then say you have too weak quads to do anything useful with them.
At least if I had a 2x high bar squat I could say it's not the quads - it's something else and address it. But in this case, I can't, because they really are too weak.
