His swing develops maximum ax speed before contact. Any energy applied to the handle after contact would be wasted. The same is true for the baseball/softball swing. The bat moves forward less than ¾ inch while in contact with the ball. So why continue to drive the hands forward - the ball is gone.

If the batter is still ridged and driving after contact, he needs to learn mechanics that will expend his energy earlier – where it counts.

Hi Jack,

I agree its not good for over-under training as you say and I have found out . But I cant see how you can say there is no strain on the limbs and joints when using the bag . When you have a bat speed of 88 mph the bag is the only thing that is going to stop it unless you delibertly put on the brakes at contact point and there is no where else for the momentum to go unless absorbed in the bag ...
Its possible I could be working the bag all wrong when using the bat speed meter. I just know it has been hard on my joints especially in the elbow.
