>>> I am 14 years old and weigh about 140 Lbs. I was wondering about how much bat speed you can gain from applying torque to your swing, and also how can you tell if you are using your hips to drive through the ball. any help is appreciated thank you for your time.<<<

> Every time you swing the bat, one of the forces you are using is torque to bring the bat-head around. The other force that helps you develop bat speed comes from the arc in the path your hands take as you swing. These are the two forces, and the only two, you apply to the bat for developing power and bat speed.

> Applying torque to the bat means the top-hand (right hand for a right-handed batter) is pushing (or pulling) the bat around the bottom hand. The average hitter applies most of their torque to the bat late in the swing. When their hands are nearing full extension, the lead hand (left hand) slows down and they can now accelerate the bat-head around by extending the right-hand past the left-hand. That is torque but it was not applied long enough, or over a long enough distance, to develop great bat speed.

Those mechanics can greatly increase your bat speed. --- Read as much of the material on the site as you can and if you have questions, feel free to ask.

Jack,

I think you are alittle confused about why the hips are turned first. Ture, they do turn the sholders. If the swing moves from the bottom up then they hips must move before the shoulders. This is a very superficial observation.

More complicated there are three addtional reasons for hip roation.

1. It creates the beining of bat speed. Its the fundemental speed that the rest of the swing adds to. Think of it this way if you are moving on a train at 60 mph and you throw a ball in the direction you are moving at 60 mph the ball is moving at 120 mph. The hips creates the speed that the shoulders, arms and hands adds too.

2. turning the hips creates a "pull" forward so that the bat is pulled on a flatter plane. Other wise the bat would remain on a downward path rather then through the ball. Think of it as similar to the golf swing, If you dont get your weight over to the left side and pull the swing forward the doward path of the club will cause the club head to be driven into the groud.

3. Turning your hips pulls the hands inside and prevents casting

4. turning the hips starts the swing with the large more poerful and easier to control muscles of the legs and back.

I hope this helps

P. S. I think you should correct the errors and contradictions in the frame by frame.
