Limit lower-body motion with flexed lead knee, foot out
The speaker describes setting the lower body so it cannot move too far: turning the lead foot out and flexing the lead knee limits how much the body can move, and keeping the foot on the ground with the heel down adds another limitation. He frames these positions as a way to restrict the range of motion of the lower body.
