Foley: As you start down, feel as if you're preparing to leap off the ground by making a squat move with your lower body. If you don't squat, you might turn your hips but you won't move your pelvis forward enough. Thrust your pelvis toward the target. Push forward and stand up: You should be at your normal standing height at the finish.
Stack & Tilt (inset): Pushing the hips forward and upward on the downswing allows the body to keep turning. The feeling is that the butt tucks under the upper body as the hips slide forward. This is a major power move because it releases the hips from their tilt toward the ball, increasing their range of motion so they can continue to turn through the shot.
