To improve your iron game using force, try to make your backswing faster than you’re used to doing and assign it a value in your mind. For example, if you’re used to taking the club back at about a 2 or 3 on a scale of 10, increase that speed up to 5. You’re trying to get the club moving quickly to start the backswing, coast to the top and then double that speed on the way down.
Going back to our example, you’ll apply double that 5 — 10 out of 10 — coming down. Unlike the takeaway where we’re adding that speed only in the first half of the backswing, you’re going to apply t that 10 all the way down and through to the finish.
This will accomplish two things: it will keep you from getting too deliberate in the backswing; and it will improve the timing of your release, which will happen more naturally as you apply force throughout your downswing.
