1. Focus is on keeping the weight on the balls of the feet
2. Using the lats and arms, to ensure the body's angles don't change prematurely
3. Bringing the bar as high as possible into the hip and onto the toes and extending
We've a bar velocity calculator at the back. It consistently shows 2.64m/sec when he extends in the hip VS about 2.46m/sec when he extends early. Now, problem is this is only 70KG and he struggles. Steffan also has a 200KG pause squat that he does with ease so I'm annoyed at how deactivated his lats are. We'll fix this soon.
