The two ball swing drill – put down two balls, set up for the outside ball and hit the inside ball. This is a great swing drill to help you train your body to keep from moving into the ball. This is great to help you get the feel for pushing away from the ball, creating space in your downswing for your hands to come through the ball and keep your hips from moving forward into the ball.
Your brain is a task master give it the task of hitting the inside ball and it’ll be impossible for your body to move into the ball or you just won’t hit it.
Exaggeration helps you understand both sides – where your swing is now and where you want your swing to be – so that you can get a better feel for what you should be doing.
