Golf Strength Training to Build Power and Increase Swing Speed

Golf is no longer just a “skill game.” The modern golfer doesn’t just show up, hit balls, and hope for the best—they train like an athlete.

Look across sports: baseball, tennis, football, even MMA. Every athlete is getting stronger, faster, and more explosive. Golf is no different. If you want to keep up—and more importantly, if you want to separate yourself—you need to develop your body the same way.

That’s where golf strength training comes in.

Rory McIlroy (pictured right) is a great example. You can find videos of him training in the gym on Youtube. He’s max trap bar deadlifting. He’s doing box jumps. Golfers are still athletes and should be training like it.

The first thing we look at with golfers is this:
Can you produce force, and can you transfer it efficiently?

Because your swing speed, your distance, and your consistency all come back to that.

Yes, golf has specific demands—rotation, mobility, sequencing—but at the end of the day, you still need to be stronger, more powerful, and more athletic. In this article, we’re breaking down exactly what a well-rounded golf performance program should include so you can build real, transferable power.

Check out one of our previous articles too on building rotational power for athletes!

Mobility: You Can’t Use What You Don’t Have

Before you ever talk about power, you need access to the positions that allow you to create it.

For golfers, that starts with:

• Thoracic spine mobility (upper back rotation)
• Hip internal and external rotation

If you’re limited here, you’re going to compensate somewhere else—usually the lower back, shoulders, or elbows. That’s where breakdown and inconsistency start.

But let’s be clear:
Mobility isn’t just about “stretching more.”

It’s about having usable range of motion that you can control and apply in your swing.

A golfer with good thoracic rotation and strong hip rotation can:

• Create better separation
• Load more effectively
• Stay consistent through impact
• Rotate through the ball with power
• Maintain balance and sequencing
• Avoid leaking energy

Mobility is your foundation—but it’s not the end goal. It’s what allows everything else to happen.

Core Strength: The Bridge Between Power and Precision

Your core is the transfer station of your swing.

You generate force from the ground. You express it through the club.
The core is what connects those two.

This isn’t about doing endless crunches.

Golfers need a core that can:

• Resist rotation (anti-rotation)
• Control rotation
• Transfer force efficiently

If your core is weak or unstable, you’re leaking energy every time you swing.

That means:

• Less club head speed
• Less distance
• More inconsistency

Strong, athletic golfers don’t just move. They control movement under speed.

Every elite golfer is going to have a really strong core, especially rotational.

Upper Body Strength: Finishing the Swing

A lot of golfers overlook this.

They think power only comes from the lower body. While that’s where it starts, your upper body is what finishes the job.

You need upper body strength to:

• Control the club at high speeds
• Maintain posture through impact
• Finish the swing with authority

We’re talking about movements like:

• Pressing (horizontal and vertical)
• Pulling (rows, pull-ups)
• Single-arm strength work

Why single-arm?

Because golf is rotational and asymmetrical. Training one side at a time builds stability, control, and better force transfer.

If you can’t control the club at the end of the swing,, you can’t express the power you’re building.

Lower Body Strength: Your Engine

Let’s make this simple:

Your legs are the engine of your swing.

If you’re not producing force into the ground, you’re leaving distance on the table.

This is where real golf strength training separates serious athletes from casual players.

Golfers should be doing things like heavy squats, deadlifts, and split squats in their golf strength training.

They need movements like this to build the raw strength needed to:

• Create ground force
• Stabilize your base
• Support rotational power

But they shouldn’t just focus on strength for their lower body. That’s not enough by itself.

Power Training: Where Speed Is Built

You can be strong and still swing slow.

That’s because strength is your potential and raises your ceiling, but power is how fast you can use it.

Golfers need to train explosively.

This is where plyometrics and explosive training come in. Things like box jumps, vertical jumps, med ball ballistics, hops, etc.

And here’s something most people don’t realize:

There’s a high correlation between vertical power and rotational power.

We see it across every rotational sport:

• Baseball and softball
• Tennis players
• Fighters (boxing/MMA)

When athletes improve their ability to produce force vertically, it carries over into how they rotate and express power.

Why?

Because both rely on:

• Rapid force production
• Ground reaction forces
• Efficient energy transfer

If you want to increase swing speed, you don’t just need stronger legs—you need more explosive legs.

That’s how you improve your rate of force production, which is a major driver of club head speed.

Putting It All Together

A complete golf performance program isn’t random.

It’s built around:

• Mobility (thoracic + hips)
• Core strength and control
• Upper body strength
• Lower body strength
• Explosive power development

Miss one of these, and you create a weak link.

And in golf, weak links show up fast:

• Loss of distance
• Inconsistent ball striking
• Increased injury risk

The goal is to train smarter and improve golfing performance as a whole with well rounded training.

Final Thoughts: Train Like an Athlete

If you’re still treating golf like it exists separate from athletic performance, you’re already behind.

The modern game demands more.

It demands:

• Strength
• Power
• Speed
• Control

And that’s exactly what a good golf strength training program is built to develop.

When we work with golf athletes, we don’t throw random exercises together. We build structured performance programs designed to help:

• Increase swing speed
• Add real distance
• Address asymmetries and mobility
• Build a strong and explosive lower body
• Move and feel like an athlete
