I can lift much heavier on hex bar than straight bar and it feels better at that. I have much more activation in my legs vs lower back for the movement. I have tried everything for straight bar, even putting the bar right against my shins (which sucks) so I could get a more centered movement on the way up but even though my form is good I still feel it in my back more and it’s not as an explosive movement as the hex bar. Can anyone help me out as to why this is? Or is it since it’s such different bars it means different muscle activation?
