Put a glove under your left arm to help you close the toe of the club and keep your left arm connected to your body
This one, two, three Rhythm Drill is great for perfecting your tempo, just even out the timing, and allow your swing to flow with the count
There should be a slight weight shift in the swing, very minimal going back to your right side on to the inside of your right leg followed by a subtle bump to your left side on the initiation of the downswing getting the weight forward and eliminating fat shots
