Got a treat for you all today.  Had Bill Miller on the podcast today to discuss swinging fast.   We talked about several components to speed development from:
1) creating core stiffness for optimal energy transferring
2) deceleration exercises to improve speed
3) lead and trail arm power development
4) using feedback to improve outcomes
If you want to hit it farther, then all you need to do is listen and start applying these principles in your training.
