What is ‘coil’ in the golf swing?
There is a reason golf coaches use the word ‘coil’ when referring to the rotation of the body. This is because your upper body is turning – or coiling – against the resistance provided by your lower body. It is the difference in the angle between your upper and lower body at the top of the backswing that is the secret power ingredient that provides real speed as you unwind through the downswing. Often, this is what the pros do well and amateurs struggle with.
To picture how it works, think of your body as a coil. At the top of the backswing it is stretched, ready to spring back through the downswing. The only way to create that stretch however, is to resist the turn of the upper body. Without any resistance (if you let your hips turn as much as your upper body) your top of backswing position will be very easy to hold. It might feel like you are making a full backswing and ready for a powerful drive back into the ball but you are actually in a weak position.
Instead, at the top it should feel as if your body is under stress and, if you pause for a few seconds, the position is hard to maintain. What you should be feeling here is power that is stored up, ready to use.
Remember, the body is the engine of the golf swing. A crucial element to that is the way you ‘coil’ in the backswing. Can you turn your upper body while resisting with your lower body? If so, you’ll unlock that special ingredient for real power. Without swinging any harder you’ll pick up crucial yardage without losing control.
