What Muscles Increase Golf Swing Speed?

By Spencer Lanoue
July 24, 2025

Every golfer wants more clubhead speed, but the common mistake is thinking it all comes from the arms. Generating true power is a full-body effort, tapping into a chain of muscles firing in perfect sequence to create that satisfying whoosh through the impact zone. This guide will break down the exact muscle groups that fuel a faster swing and give you actionable exercises to build them, helping you unlock the distance you know you have in the tank.

It's a Full-Body Job: Understanding the Kinetic Chain

Before we jump into specific muscles, let's talk about the big picture. The golf swing is a fantastic example of a kinetic chain. Think of it like a whip. The power doesn't start at the tip of the whip, it starts with a large movement at the handle, and that energy accelerates down the line, getting faster and faster until the tip cracks. Your body works the same way.

Maximum swing speed doesn’t come from trying to swing your arms faster. It comes from an efficient sequence of movement, where power is generated from the ground up. You use your big, strong lower-body muscles to create rotational force, which is then transferred up through your stable core, into your torso and shoulders, down your arms, and finally, into the clubhead. Each link in the chain adds speed. If one link is weak, the chain breaks, and you lose power. So, our goal isn't just to get strong, it's to get strong in the right places to power this sequence.

The Core: Your Swing's Engine Room

If the golf swing has an engine, it’s your core. This group of muscles - including your abdominals, obliques (the muscles on your sides), and your lower back - is ground zero for power. Your core stabilizes your body and, most importantly, connects your lower body's power to your upper body's swing. It’s the centerpiece of your rotation.

When you coil in your backswing, you are loading your core like a spring. When you start the downswing and unwind, a powerful core lets you unleash that stored energy explosively. A weak core, on the other hand, causes a disconnection between your hips and shoulders, leading to a loss of speed and consistency. Every golfer who's serious about speed starts right here.

Actionable Core Exercises for Golfers

  • Rotational Medicine Ball Throws: This is a perfect golf simulation. Stand sideways a few feet from a solid wall, hold a medicine ball (start light, maybe 6-10 lbs) at your waist, and mimic your golf swing. Rotate away from the wall (like a backswing) and then explosively turn your hips and core to throw the ball against the wall. Catch it on the rebound and repeat. This trains rotational power like nothing else. Do 3 sets of 8-10 reps on each side.
  • Planks: The classic plank is fantastic for building the kind of deep core stability you need to stay in your posture throughout the swing. But let’s make it more golf-specific. Try a Plank with a Reach. Get into a solid plank position, and without letting your hips rock, lift one arm straight out in front of you and hold for two seconds. Place it back down and switch arms. This adds an anti-rotation element, forcing your obliques to fire to keep you stable.
  • Cable Wood Chops: Set a cable machine pulley to a high position. Stand sideways to it, grab the handle with both hands, and pull it down and across your body in a diagonal chopping motion, rotating your torso and hips. This perfectly mimics the crunching and turning motion of the downswing. Perform 3 sets of 10-12 reps per side.

The Glutes and Legs: Building Your Power Foundation

Ask any long-drive champion where their power comes from, and they won't point to their arms. They’ll point to their legs and backside. Your glutes (butt muscles) are the single largest and most powerful muscle group in your body. Along with your hamstrings and quads, your lower body is responsible for creating ground force reaction - the way you use the ground for leverage.

As you start your downswing, think about how pros seem to "squat" for a split second. They are driving into the ground with their legs to initiate the unwinding of the hips. This push creates immense rotational speed. Without a strong and stable lower body, you have no firm foundation to turn against, and all that potential power is lost.

Actionable Leg and Glute Exercises

  • Goblet Squats: Squats are the king of lower body exercises. We prefer Goblet Squats for golfers because holding a dumbbell or kettlebell against your chest forces you to keep an upright torso and engage your core, just like you need to in your golf posture. Focus on lowering your hips back and down with control, keeping your chest up. Do 3 sets of 8-12 reps.
  • Glute Bridges: Many golfers have "sleepy" glutes from sitting too much. A Glute Bridge is the perfect way to wake them up. Lie on your back with your knees bent and feet flat on the floor. Drive through your heels and lift your hips toward the ceiling, squeezing your glutes hard at the top. This exercise isolates the glutes and teaches you how to fire them for power. Do 3 sets of 15-20 reps.
  • Kettlebell Swings: If there's one explosive exercise for golf, this is it. The kettlebell swing trains the powerful hip-hinge motion that is fundamental to generating speed. It builds explosive power in your glutes and hamstrings and connects that power through your core. Focus on form over weight! The movement should be a sharp "snap" of the hips, not a lift with the arms. Do 4 sets of 15 powerful swings.

The Lats & Back: Creating Width and Speed

This is the secret weapon for a lot of power hitters. Your back, specifically your latissimus dorsi (the "lats" that give you that V-shape), acts as the transmission for your golf swing. These large muscles run from your mid-back up to your upper arm. They are responsible for creating width in your backswing - a wider arc means more distance for the clubhead to travel and build up speed.

In the downswing, it's the lats that help you powerfully pull the club down from the top, maintaining that crucial angle between your arms and the club shaft (what golfers call "lag"). A strong back and stable shoulders not only add to swing speed but also protect your body from injury.

Essential Back and Lat Exercises

  • Dumbbell or Barbell Rows: This is a foundational back-strengthening movement. By pulling the weight toward your chest, you directly target the lats and rhomboids. Maintaining a flat back during the movement also strengthens the spinal erectors, which are an important part of your core. Do 3 sets of 8-12 reps.
  • Lat Pulldowns: As the name suggests, this machine exercise directly targets the lats. It helps you build that "pulling" strength that is so important for the downswing. Focus on pulling the bar down to your upper chest while leaning back slightly. Perform 3 sets of 10-12 reps.
  • Band Pull-Aparts: The smaller muscles of your upper back and rotator cuffs are essential for stability and health. Hold a light resistance band in front of you with both hands, arms straight. Keeping your arms straight, pull the band apart until it touches your chest. This move is fantastic for improving posture and protecting your shoulders. Do 3 sets of 15-20 reps.

Wrists & Forearms: The Final Speed Transmitters

Finally, we get to the arms. While your forearms and wrists don’t create the majority of the power, they are the final delivery system. They transfer all the force you've generated in your body into the clubhead. Strong hands and forearms prevent the club from "casting" or being released too early at the top of the swing, which is a major speed killer. They also give you the control to square the clubface at impact, even at high speeds.

Think of it this way: your glutes and core load the cannon, but your forearms and wrists ensure the cannonball fires straight and true at maximum velocity.

Targeted Grip and Forearm Exercises

  • Farmer's Walks: The simplest exercise on this list and one of the best. Pick up a pair of heavy dumbbells or kettlebells and walk. That’s it. This will torch your grip and forearm strength while also building overall core and back stability. Walk for a set distance (30-40 yards) or for time.
  • Wrist Curls: A classic for a reason. Sit on a bench and rest your forearms on your thighs with your palms facing up, holding a light dumbbell. Let the dumbbell roll down to your fingertips and then curl it back up, squeezing your forearm. Do reverse wrist curls (palms down) as well to work both sides of the muscles. Do 3 sets of 15 reps.

Final Thoughts

Building a faster, more powerful golf swing is about training your body as a complete system, not just swinging harder with your arms. By strengthening your core, glutes, and back, you build the engine that drives speed, allowing your arms and hands to direct that power correctly through the ball.
