Golfers can achieve greater power and speed in their swing by creating coil in the backswing. Professional golfers turn their shoulders back twice as much as their hips during the backswing. This separation between the shoulder and hip turn creates coil, which helps produce speed in the downswing. Many amateur golfers struggle to create this coil because of a poor setup and a misunderstanding of proper body turn. With a good setup and a better understanding of the proper body turn, you can achieve maximum coil and power in your swing.
When golf instructors talk about coiling in the backswing, they’re discussing “the turning of the body away from the target,” says PGA pro Mark Blakemore. All else being equal, the more you coil your body during the backswing, the more swing speed you’ll generate in the downswing -- but only if you coil properly. Coiling your body improperly will rob you of power. Golf instructors recommend a variety of methods to help players coil correctly.
If a good backswing lays the foundation for sound golf technique, then a strong downswing is the heart of your stroke. While many golf instructors advise casual players to keep their swings simple and repeatable, there are a few fundamentals on which any player should focus to develop a solid downswing.
If your arms don’t remain in front of your chest during the backswing it likely means that you’re not rotating your body sufficiently. A lack of body rotation means, at the very least, that your hands won’t be as high as they should be at the top of your backswing. This defect alone will rob your swing of power. By keeping your arms in front of your chest you help ensure that your body moves in the most efficient manner and generates maximum power.
The golf swing involves numerous moving parts and almost every joint in the body. The left foot and ankle (for a right-handed golfer) aren’t typically areas of focus. But their movements may demonstrate whether other parts of your backswing are working as they should. A bit of left foot movement may also help some players add power.
