Having a fluid swing with the proper weight training can only enhance your chances up at the plate. I always was a firm believer in bat speed, but myself I concentrated more on technique. I knew I already had great bat speed. In the hitting zone portion of my web site I have some links that I think you will find very helpful in obtaining maximum bat speed along with producing a great fluid swing. Below is a photo of Larry Carter doing some dumbbell presses. Larry who was one of the strongest people to play the game has such a powerful swing that he can swing a softball over 110 miles per hour. Put that together with a good fluid swing and you can understand why he hits the ball so far.
