Timing: The lead hand swings allow a hitter to establish proper timing and power with the lead side of the body, giving the hitter proper contact with the ball. The follow hand swings establish the feeling of throwing the bat at the ball.
Procedure: Hit off a tee, imaginary ball, or soft-toss. When executing swings with the lead hand, you should concentrate on keep the hand above the plane of the ball. If the lead hand drops under a pop out, strike out, or fly out will usually occur. The hitter must also turn the hips quickly for proper timing and power. The lead elbow should not extend fully before contact with the ball, since that will promote a slow bat due to an excess of arm arc in the swing.
By concentrating on keeping the lead hand on top of the ball and turning the hips quickly, a hitter can establish proper timing and power with the lead side of the body. The lead hand/follow hand action creates timing and power. Both hands should snap straight into the ball precisely the same instant. This will help you establish proper bat speed and control.
