The golf swing is a complex interplay of body and club, and the coil is the true engine of power at its heart. The coil is the rotation of the upper body (shoulders, torso, hips) during the backswing, creating a spring-like tension that is released on the downswing. This coiling action increases clubhead speed and improves consistency, keeping the body in sync. To achieve a proper coil, the upper body must turn against the resistance provided by the lower body, with the shoulders turning first, followed by a gradual rotation of the hips. This intricate dance of the body and club is a delicate balance that, when mastered, can add significant power and accuracy to your golf swing.

What You'll Learn

The coil is the rotation of your upper body (shoulders, torso, hips) during the backswing
The coil is a fundamental aspect of the golf swing, and it is the rotation of your upper body (including your shoulders, torso, and hips) during the backswing. This rotational movement is what generates power in your swing, as it builds and stores energy that can be released towards the target during the downswing.
To execute the coil effectively, it is important to understand the independent roles of your shoulders and hips. The movement should begin with a turn of your shoulders, followed by a gradual rotation of your hips. Imagine your left shoulder trying to touch your right hip, creating a full rotation in your upper body. Your hips should lag slightly behind your shoulders, building tension and energy in your upper body, like a tightly wound spring ready to be released.
It is also crucial to maintain the stability of your lower body while coiling your upper body. This resistance in your lower body provides the necessary tension for a powerful release. Think of your body as a coil, stretching during the backswing and then springing back during the downswing.
Practicing the "winding drill" can help you improve your coiling technique. Stand in your address position without a club, and let your arms hang. Cross your left wrist over your right so that the backs of your hands are touching. Keeping your lower body stable, rotate your right side away from the target while resisting with your left arm. This exercise will help you feel the coiling action in your core and back muscles, improving your power and consistency during the swing.
Additionally, you can try the "impact bag drill" to enhance your coil. Start in the address position with your hands on an impact bag. Move your arms back as if you're throwing the bag forward while keeping it level. This drill will help you maintain your body shape and experience the natural coiling action without needing extra movement.

Keep your left arm extended
Keeping your left arm extended during your golf backswing is crucial to achieving a powerful and effective swing. Here are some detailed instructions and tips to help you master this technique:
The left arm plays a vital role in the golf swing, and maintaining its extension can make a significant difference in your performance. A straight left arm creates width in your swing, allowing you to generate more speed and power. This additional power comes from the ability to store and release energy during the backswing and downswing. Think of it like cranking a catapult into firing position—you're building up energy that can be unleashed towards the target.
To achieve this extension, focus on keeping your left elbow straight during the backswing. This doesn't mean locking your elbow rigidly; instead, aim for a slight hinge to maintain the flow in your swing. As you start the backswing, keep your left arm close to your body until it becomes parallel to the ground, and then allow your wrists to hinge. This movement ensures that your arms and body are "connected," with your body driving your turn away from the ball rather than your arms.
A useful drill to improve your left arm extension is the opposing forces drill. Stand in your address position without a club, letting your arms hang naturally. Cross your left wrist over your right so that the backs of your hands touch. Now, while keeping your lower body stable, rotate your right side away from the target while resisting with your left arm. This drill helps you feel the coiling action in your core and back muscles, teaching your body to coil and build energy during the backswing.
It's important to note that the length of your swing is not determined by how far you can swing your arms but by how much you can rotate your body. If you feel your left arm bending at the top of your swing, it's likely because your body has stopped rotating, and you're relying too much on your arms for power. Focus on rotating your lower body more, which will give your upper body more room to turn while keeping your left arm extended.
By incorporating these techniques and drills into your practice, you'll be able to consistently achieve a straight left arm during your golf backswing, resulting in more powerful and effective shots.

Bend your left leg and rotate your torso
To coil in a golf backswing, you need to rotate your upper body (shoulders, torso, hips) while swinging the club back. This creates a powerful, spring-like tension that can be released on the downswing, increasing club head speed and improving consistency.
To achieve this coil, it is important to bend your left leg and rotate your torso. Here's a step-by-step guide:
- Start with your address position: Stand over the ball with your feet shoulder-width apart, knees slightly bent, and your weight balanced evenly on the balls of your feet.
- Begin the backswing: As you take the club back, focus on turning your shoulders away from the target. Imagine your left shoulder trying to touch your right hip, creating a full rotation in your upper body.
- Engage your hips: As your shoulders continue turning, gradually rotate your hips as well. Ensure your hips lag slightly behind your shoulders to create that coiled tension.
- Bend your left leg: As you rotate your torso and engage your hips, maintain a bend in your left leg. This bend provides the necessary torque and pressure on the front leg for power in your swing.
- Shift your weight: As you coil your upper body, shift your weight to the left side. This weight transfer is crucial for generating power and can be felt by practising drills like throwing an impact bag.
- Uncoil and release: As you start the downswing, unleash the stored energy by uncoiling your upper body and rotating your lower body toward the target. This release of tension will propel the clubhead forward with speed and power.
Remember, the coil is a delicate balance of rotation and stability. While you bend your left leg and rotate your torso, keep your left arm extended and your head still, focusing on the ball. Practise this coil drill to improve your backswing and add power to your golf swing.

Keep your lower body stable
Keeping your lower body stable during the backswing is crucial for maintaining balance and creating power in the golf swing. Here are some tips to help you achieve that stable lower body coil:
Maintain a Steady Base
Keep your lower body quiet and stable throughout the backswing. Focus on maintaining the flex in your right knee (for right-handed golfers) and avoid any excessive movement or straightening of that leg. This provides a stable base for you to coil your upper body against, storing energy for the downswing.
Resist the Twist
As you rotate your upper body during the backswing, make sure your lower body resists this rotation. Your hips should move minimally, only slightly rotating to allow for the necessary coil. Imagine your lower body remaining firm and rooted to the ground as your upper body winds up.
Control the Hip Movement
The key to a stable lower body coil is controlling the movement of your hips. Your hips should primarily move laterally, shifting your weight to your right side (for right-handed golfers), rather than rotating aggressively. This lateral shift provides stability and sets you up for a powerful downswing.
Engage Your Core
Stabilizing your lower body also requires a strong core. Engage your abdominal muscles to maintain a solid foundation throughout the swing. This helps you resist unnecessary movements and maintain control, ensuring that the coil happens in the upper body while the lower body remains relatively quiet.
Practice Drills
One helpful drill is to swing with your feet together. This forces you to focus on stability and balance, promoting a quiet lower body. Another drill is to use a resistance band tied around your legs, just above your knees. Practice your backswing while resisting the pull of the band. This helps reinforce the feeling of a stable, controlled lower body coil.
By focusing on these techniques, you'll develop a more stable lower body during the backswing, leading to improved balance, consistency, and power in your golf swing.

Engage your hips gradually
To engage your hips gradually during the golf backswing, you should first focus on turning your shoulders away from the target. Imagine that your left shoulder is aiming to touch your right hip, creating a full rotation in your upper body. As your shoulders continue to turn, you can gradually start to rotate your hips. It is important to not overdo the hip rotation; your hips should remain slightly behind your shoulders to create a coiled tension. This coiling action will help you maintain balance and control throughout your swing, keeping your body in sync.
The golf swing is a delicate interplay between your body and the club, and the coil is at the heart of this dance. It is this rhythmic winding up of your torso that allows you to build and store energy, which can then be released with power and speed on the downswing. The coil is what gives your swing its force, like a tightly wound spring being released.
To achieve this coiling effect, your upper body should turn away from the target during the backswing, while your lower body resists this rotation. This resistance is key to building up the energy that will be unleashed on the ball. The difference in the angle between your upper and lower body is what creates the power in your swing.
To help you feel this coiling action, you can try a drill where you stand in your address position without a club and let your arms hang. Then, cross your left wrist over your right so the backs of your hands are touching. Keeping your lower body stable, rotate your right side away from the target while resisting with your left arm. This will help you understand the opposing forces at play in the coil, and how it can add power to your swing.

Frequently asked questions
The coil in a golf backswing is the rotation of the upper body (shoulders, torso, hips) against the resistance provided by the lower body.
The coil is important because it increases club head speed and improves consistency. By winding up the body and storing energy, the downswing can be propelled with tremendous speed.
To coil your body, you must first turn your shoulders, followed by a gradual rotation of your hips. Your hips should lag slightly behind your shoulders, creating tension.
One drill is to stand in your address position without a club and let your arms hang. Then, cross your left wrist over your right so the backs of your hands are touching. Keeping your lower body stable, rotate your right side away from the target while resisting with your left arm. You can also try throwing an impact bag to feel the coil.
A common mistake is to “over-rotate” and make it a “turn” instead of a coil. This leads to less speed and a loss of body shape during the swing. Another mistake is letting the lead arm collapse during the backswing, making it difficult to hit the ball solidly.
