I deadlifted heavy with a straight bar for the first time in a long while (5-6 months). My best pull with a conventional stance is 475. I decided to go sumo the other day(I never pull sumo). Long story short I worked my way up to 500 lbs doing singles. I got 500 moving off the ground but hit a sticking point right below my knees and had to drop it. I've never budged a weight off the floor before and not been able to lock it out. I want to try some rack pulls to help my sticking point, but do I rack pull with a sumo stance? Where would be the best height? right below my knee where I stalled?
I really don't know how to tackle this because I've never really pulled sumo style. Let me know guys, I'm really looking forward to pulling 500 soon.
