Coil the lower body by drawing the right leg back
The speaker teaches a feel for creating time in the backswing by coiling the lower body rather than adding more turn. He gets the bottom half to coil by drawing the right leg back, producing what he calls symmetrical knee work - as the right knee goes back, the left knee goes forward. He frames it as something you need to feel, not just a position.
