Want to reduce the errors in your game? Work on your non-dominant shoulder. It will greatly improve your body's positioning as you execute the stroke - reducing errors and increasing accuracy.
This is part of our Project 4.0 series of videos to help you become the best player you can be. The principles here apply can be used by players at all levels of play. Thank you Elke for your help putting this video together.
