In all honesty Al, that was horrendous form. I don't know if i'm even watching the same video as everyone else here.
You're not going to transition to Sumo pulling like that. You know you need to arch that back or at very least get it flat, that way you have the correct transfer of force from the bottom up to take advantage of the gear.
There's no point in lifting a weight in the gym just for the sake of lifting it, no point at all. Execute the lift in the correct manner in training. Just get it up anyway you can in competition.
