Stall the hands at impact to square the face
The speaker explains that when you are putting force into the ground, if this hand keeps moving you can never square the face. Instead it needs to be a stall, a pull up, to get the club square, and he says this is how he can swing so hard and line the face up every time. His cue is to swing really hard and stall the hands at impact.
