I feel like I will fall over if I do pendlay rows.
I love Pendlay Rows, while I find it hard to maintain absolute stiffness in my hip joint I arch my back as tight as possible and put myself at an angle that I can really feel the stretch in my hamstrings, almost as if I was doing a RDL. I find that keeps me pretty stable.
I always feel like there's some momentum carryover from pulling from the floor though, if you contract your upper back at an explosive speed naturally that momentum wants to shift you backwards and it feels limiting to try and counter act that motion while puling in the opposite direction.
I swear lats were mainly for aesthetics? As well as overhead and pressing stability.
I'm currently discovering that my weak-ass lats are a massive disadvantage in the O-lifts, especially in the clean. Since I can't engage them very well it means I often don't pull the bar close enough to my body in the 2nd pull and end up catching the bar really far in front of me. Nearly ripped my torso from my waist doing that the other day, but my lower back is so much stronger that I mong-strengthed it up and did a legal lift. Got told to stop deadlifting so much lolol.
