One of the most important things you can do for your swing is to get your hips and shoulders into it. Try out this drill to perfect your swing.
Items needed for drill:
Rubber Playground Ball (slightly smaller than a basketball)
How to perform the drill:
Place the rubber playground ball against your chest and hold the ball in place with your arm that is facing the pitcher
Take your normal batting stance
When swinging, focus on driving your hip through the ball. Your shoulders will naturally dip so that your back shoulder is below your front shoulder. Both of these combined will help your launch angle during normal swings
