Its my most sensitive lift. I've been putting lbs on squats, deads and all my upper back/shoulder shit no problem. But with bench, for some reason if I'm not feeling 120% it just doesn't move up anywhere as quickly as anything else. I recently revamped my form, which helped, but even still, it's a struggle. I usually stall out towards the middle of the rep, which I guess means triceps, which I'm working on.
