Build Core Strength, Activate Your Glues, and Improve Thoracic Mobility
For many golfers, turning 40 doesn’t mean losing distance or power—it simply means your training needs to become more intentional.
As a TPI-certified golf fitness professional, I see the same pattern repeatedly with golfers over 40. Distance loss, back discomfort, and reduced rotation usually come from three things:
- Weak or underactive glutes
- A core that isn’t stabilizing the golf swing
- Limited thoracic spine mobility
When these areas are addressed properly, golfers often regain swing speed, improve consistency, and reduce the risk of injury.
The good news is that you don’t need complicated training routines. A few targeted exercises can dramatically improve the way your body supports the golf swing.
Why Golf Fitness Changes After 40
After 40, two physical changes begin to affect most golfers:
1. Muscle activation decreases
The glutes and deep core muscles often become less active, which forces the lower back to work harder during the swing.
2. Mobility decreases
The thoracic spine—the mid-back area responsible for rotation—gradually stiffens with age and sedentary work.
When the thoracic spine stops rotating well, golfers compensate by over-rotating the lower back, which can lead to discomfort or injury.
This is why a golf fitness program for golfers over 40 should focus on:
- Glute strength
- Core stability
- Thoracic spine mobility
Let’s look at three exercises I frequently use with golfers.
1. Glute Bridge
The glutes are the primary power generators in the golf swing. Unfortunately, they are often inactive in golfers who spend long hours sitting.
The glute bridge is one of the simplest ways to re-engage these muscles.
How to perform it
- Lie on your back with knees bent and feet flat on the floor.
- Keep your arms relaxed at your sides.
- Drive through your heels and lift your hips toward the ceiling.
- Squeeze your glutes at the top for two seconds.
- Lower slowly.
Recommended sets: 3 sets of 10-12 repetitions
Golf benefit: Strong glutes improve ground force production, helping generate more clubhead speed and protecting the lower back.
2. Dead Bug Core Exercise
The core’s job in the golf swing is not just strength—it’s stability.
The dead bug teaches your core to stabilize the spine while the arms and legs move, which closely mimics the demands of the golf swing.
How to perform it
- Lie on your back with arms extended toward the ceiling.
- Lift your legs so your knees are bent at 90 degrees.
- Slowly extend one arm and the opposite leg toward the floor.
- Keep your lower back pressed gently into the ground.
- Return to the starting position and switch sides.
Recommended sets: 3 sets of 8-10 reps per side
Golf benefit: This exercise improves core control, helping maintain posture and spine stability throughout the swing.
3. Thoracic Spine Rotation Stretch
The thoracic spine is responsible for most of the rotational movement in the golf swing.
If this area becomes stiff, the body compensates by rotating excessively through the lower back or shoulders.
A simple thoracic rotation stretch can restore movement where golfers need it most.
How to perform it
- Lie on your side with knees bent and stacked.
- Extend both arms straight in front of you.
- Slowly rotate your top arm across your body, opening your chest.
- Follow your hand with your eyes as you rotate.
- Pause for a few seconds before returning.
Recommended sets: 6-8 rotations per side
Golf benefit: Improved thoracic mobility allows for better shoulder turn, which can increase both swing efficiency and power.
Building a Simple Golf Fitness Routine
Golfers over 40 don’t need long workouts to see results. Consistency is far more important than volume.
A simple routine might look like this:
- Glute Bridge – 3 sets
- Dead Bug – 3 sets
- Thoracic Rotations – 6–8 reps per side
Perform this routine three times per week, and many golfers begin to notice improved mobility and better body awareness during their swing.
Final Thoughts
Golf fitness for golfers over 40 should focus on maintaining mobility and building the right kind of strength.
By strengthening the glutes, stabilizing the core, and improving thoracic spine mobility, golfers can maintain power and continue playing strong for decades.
The goal isn’t simply to swing harder—it’s to move better.
When the body functions efficiently, the golf swing becomes both more powerful and more sustainable.As a golf fitness professional trained through the Titleist Performance Institute (TPI), I’m often asked the same question every Winter:
“What should I actually be doing in the off-season?”
The short answer: this is your most important training window of the entire year.
The longer answer—and the one that truly matters—is that the off-season is when golfers can finally address physical limitations, build usable strength, and create a body that supports a repeatable, powerful swing.
Unlike in-season training, where the goal is maintenance and recovery, the off-season is where real change happens.
