One of my favorite swing “keys” is to imagine a pop can or a wet sponge underneath your front foot. As you approach the end of your backswing, think of crushing the can or squeezing the water out of the sponge. If you’re still struggling to find ball then turf contact, put a little more weight into the can/sponge at address. This added forward weight at address will help “prime” your downswing move, while ensuring you’re not swaying too much off the ball into the backswing.
