I didn't feel like making a new thread so I'm just going to ask here. I watched some videos of people doing zercher deadlifts since I was curious as how one would do it without hurting their back. But it seems like every person I watch, their backs become extremely rounded as they go up. How can this lift be good for your back? Were they just doing it wrong?
I've always loved zercher squats but I never knew a zercher DL existed.
