Most beginners struggle to understand how the body moves during the putting stroke, and we tend to see the wrists and elbows breaking down quite a bit. Try this drill: Start without a putter – place an alignment stick across your chest and under your armpits. Place your palms together in front of you and get into your putting posture. Start to move the hands back and through and notice how your shoulders are rocking in unison with your hands. Once comfortable with this, put the putter in your hands and try to make the same motion. Keep your wrists and elbows firm, and notice how your whole upper body moves as one piece. Once comfortable with that, try putting some balls across the carpet with that alignment rod still running across your chest.
