Power - Gaining more power is something every hitter can benefit from. Now that the body is in the correct position, hitters can start to reach their full potential. Being able to use the lower half correctly makes hitters hit the ball harder. This will help them get more hits due to the fact that you don't leak power in your swing and can hit the ball farther.
Adjustability - Something that every hitter needs is the ability to adjust to different speeds and locations. With the hitter now being in a more loaded and athletic position, they can make decisions a little bit later, therefore being more accurate with their bat.
Swing Direction - The direction of the swing truly starts with the lower half. If the lower half is leaking open the hitter has to compensate with their shoulders. This results in a lot of pulling off the ball and spinning away from the strike zone. Learning how to keep the lower half in the right position is key and will help hitters get the bat on the ball and hit it hard!
