In the Crossover Drill, we're going to have our hitters set up with their front foot crossed over their back foot and getting into that good "K" posture.
With a good "K" Posture you'll notice the hitter leans forward so the front shoulder is a little below the back shoulder. If you have hitters that struggle with maintaining good posture and collapsing their backside this is a great drill for them. You'll notice that when doing this drill it is very difficult for them to collapse that back side.
When this drill is done correctly, you're going to see a little bit of tilt in their shoulders and their body maintain a good posture. When the hitter moves toward the ball they should feel like they're about to fall forward. At The Vault we call this a controlled fall in your stride and swing which sets the hitter up in a perfect launch position.
