AhNope. As a person who’s always had low back disc problems that movement makes me nervous. Seems like the part where you contact the bench could be jarring to everything down there.
Well I haven't gotten back in the gym yet but I think it stops you from going too deep in your squat so that you don't compromise your posture.
I'ma definitely try it the first day I get back and slowly build my way up to where I was before I stopped going
