Tip 49: Use Both Sides

  For many players, the left arm and side are weak and dominated by the right side on the downswing and through impact. This right-side dominance leads to poor extension and many other swing flaws. To ingrain a proper feel, swing lightly with the left arm only. As you do this, check how the arm extends freely through the impact zone. Now, add the right arm with a light grip and try to maintain the extended feeling you just had. You’ll immediately feel it getting more restricted, but let it go and keep using that left arm and side along with the right. You’ve got two sides—use them both!
