Many times we shy away from doing the hard things that we need to do to improve. For example, in golf everyone is trying to get more distance. Many try to get there by getting a super light driver or buy the latest get long quick training aid. In reality, you get longer by training the golf muscles hitting golf balls. One of the best drills for both distance and quality of the strike is one arm golf shots. You simply can’t consistently make good contact if you don’t have your arm in sync with the torso. If you can sync your torso and arm swing you will hit better shots.
