I'll start: Sumo deadlifting like in pic related is fucking retarded.
>Arm position
Arms go straight down. Having them at an angle increases the ROM. The only excuse to ever not have the arms reach straight down is when you're deadlifting regular with a wide stance and your legs are standing in the way of your arms.
>Toe position
The toes on the sumo deadlift point outwards. That's easy to overlook, but I know from experience that it's pretty damn important. This decreases the angle of the lower back and it makes activation of the quads easier. Considering that sumo is all about maximum quad-activation and decreasing the back angle as far as possible, not pointing your toes outwards is absolutely fucking retarded.
Funny thing is, the guide I got this picture from mentioned toe positioning, but the model did it wrong, anyway.
