Step two is the most important step and it is to start by making small quarter swings without hitting balls. The vast majority of your reps should be done in step two. This is a crucial step to develop the feel for your left hand leading through impact. This step is not about creating a huge lag angle, it's simply to

1. Develop the feel of how your lead hand should work through impact
2. The feeling of releasing the club

It's important to do this step not hitting balls. When the ball is in front of you, your brain is worried about hitting the ball and not making a swing.

Small Swings

Take your stance and make a small quarter backswing and in the downswing let go of the club with your trail hand at impact as the club releases and passes by your hands. Many instructors use the phrase toe up to toe up. Meaning that in the backswing your clubhead will be toe up to the sky and just after the release the club will release/rotate to toe up.

If you are having trouble getting the club toe up in these quarter swings, you are simply not allowing the club to release and pulling the club through impact too hard.

A major key for this step is a one piece takeaway. One of the most common mistakes amateurs make is that they do not create enough upper body rotation in the backswing but more specifically the takeaway. You should aim for about 45 degrees of upper body rotation by the time the club is parallel to the ground. Feel your body rotating first, dragging your hands along with it.

Smoothly transition into the downswing, letting the club fall into impact. Remember, this is about swinging correctly not swinging hard. Let go of the club with your trail hand as you get to impact.

The goal of this step is to feel what it's like to have your lead hand controlling the swing through impact. A key part of the release is allowing the club to release and pass by your hands. If you look at professionals hands during the release, their glove logo will turn to point directly behind them. This becomes crucial as you get to bigger swings.

I recommend looking at a slow motion video of either Fred Couples or Vijay Singh's swing. You will see that they literally let go of the club with their right hand through impact and get a completely free flowing release. 

Common Mistakes:

Backswing:

• Not enough shoulder turn

• Doing too much with your hands. Yanking the club back with the right hand. Keep your hands and wrists neutral.

Downswing:

• Trying to "hit" with your right hand/arm

• Over pulling the club through impact, resulting in the club face open to the sky rather than toe up at the end of these small swings
