How to Improve Golf Endurance

By Spencer Lanoue

Feeling that back-nine burnout is one of the most frustrating things in golf, turning a great round into a grind you just want to end. This isn't just about a lack of fitness, it's about a complete energy breakdown that affects your body, your focus, and your swing. This article will show you how to improve your golf endurance by focusing on golf-specific strength, smart on-course energy preservation, and the mental stamina needed to finish as strong as you started.

Beyond the Gym: What Golf Endurance Really Means

When golfers think about endurance, their minds usually go straight to running or long sessions on an exercise bike. While cardiovascular health is important for walking 18 holes, true golf endurance is more specialized. It's the ability to make a sound, athletic golf swing on the 18th hole that feels just as controlled and powerful as the one you made on the 1st tee. This requires a mix of physical stamina, mental focus, and, most importantly, swing efficiency.

Think about it: an inefficient golf swing that relies on jerky, isolated movements of the arms and hands is unbelievably tiring. You’re essentially fighting your body with every move. Conversely, a smooth, rotational swing powered by your core and hips - like we always teach - is repeatable and dramatically less exhausting. You’re using your body’s natural engine, not trying to force the club with small muscle groups. This efficiency is the foundation of golf endurance. When you conserve energy in the swing itself, you have more left in the tank for the final stretch of holes, where rounds are often saved or lost.

Physical fatigue almost always leads to mental errors and poor decisions. You stop committing to shots, you choose the wrong club, and you get sloppy with your short game. Building real golf endurance is your defense against that costly back-nine collapse.

Building a Golf-Ready Body

Forget trying to look like a bodybuilder. Our goal is to build a resilient, mobile, and stable body that can support a rotational golf swing for four-plus hours. This doesn't require spending hours in the gym, it just requires focusing on the right things.

Focus on Core Strength and Stability

Your core - the complex web of muscles in your abdomen, hips, and lower back - is the engine of your golf swing. A strong, stable core does two things exceptionally well: it transfers energy efficiently from your lower body to your upper body for effortless power, and it protects your back from the rotational forces of the swing. The weaker your core, the more your arms, shoulders, and lower back have to compensate, leading to miss-hits and fatigue.

Here are a few simple exercises to build a solid foundation:

  • Plank: The gold standard. Get into a push-up position but rest on your forearms. Keep your body in a dead straight line from your head to your heels. Don’t let your hips sag. Hold for 30-60 seconds. This builds pure stability.
  • Glute Bridges: Lie on your back with your knees bent and feet flat on the floor. Squeeze your glutes and lift your hips until your body forms a straight line from your shoulders to your knees. This activates the most powerful muscles in your lower body, which are vital for your swing.
  • Bird-Dog: Start on all fours. Extend your right arm straight forward and your left leg straight back simultaneously, keeping your back flat. Hold for a second, then return to the start. Alternate sides. This teaches your body to stay stable while your limbs are in motion - exactly what happens in a golf swing.

Mobility is Your Secret Weapon

Strength is good, but if you can't turn, you can't swing efficiently. Poor mobility, especially in your hips and thoracic spine (your upper back), forces your body to find workarounds. This might mean swaying instead of rotating or using your arms too much - all of which are exhausting and inconsistent. Improving your mobility lets you make a full, fluid turn with ease.

  • Thoracic Spine Rotations: On your hands and knees, place one hand behind your head. Rotate that elbow down toward your opposite wrist, then rotate it up toward the ceiling as far as you can, following with your eyes. This directly improves the upper-body rotation needed for a deep backswing.
  • 90/90 Stretch: Sit on the floor with your front leg bent at 90 degrees in front of you and your back leg bent at 90 degrees to the side. Keeping your chest up, gently lean forward over your front shin to feel a stretch in your hip. This improves hip mobility, allowing for a better lower-body turn.

Don't Forget Cardiovascular Health

Walking five miles, often up and down hills, while carrying a bag or pushing a cart is no small feat. Getting easily winded takes your head out of the game and rushes your process. Even if you ride in a cart, cardiovascular fitness helps with recovery between shots and maintains mental clarity.

You don't need to run a marathon. Simply committing to 20-30 minutes of brisk walking three times a week can make a massive difference. Better yet, choose to walk the course a couple of times a month instead of taking a cart. You'll gain a better appreciation for the rhythm of the game and build functional endurance at the same time.

Fueling Your Round and Managing Energy

What you do on the course is just as important as the conditioning you do off it. Even the fittest golfer will crash if they don't manage their energy correctly during a round.

Hydration and Nutrition: Your On-Course Lifeline

This sounds basic, but it's the most common mistake I see. Dehydration is a performance killer. It leads to headaches, loss of focus, and muscle cramps. The rule is simple: drink before you feel thirsty. By the time you feel thirst, your performance is already declining. Start hydrating the day before your round and aim to drink a bottle of water every 4-5 holes.

Food is fuel. But the wrong food can be worse than no food. Avoid the syrupy sports drinks, candy bars, and hot dogs at the turn. These cause a huge sugar spike followed by a dramatic crash, usually right around the 13th or 14th hole. Instead, think about sustained energy. Pack snacks like:

  • Almonds or other nuts
  • Bananas
  • Beef jerky
  • Low-sugar protein bars
  • Peanut butter crackers

Eat a small amount every 4-5 holes. This strategy keeps your blood sugar stable and your energy levels consistent from start to finish.

The Pre-Shot Routine: Your Personal Rest Stop

A golf round isn't a continuous sprint, it's a series of short bursts of intense focus and physical effort, followed by long recovery periods (the walk to your ball). Many golfers waste enormous energy by staying mentally "on" the entire time, stressing over their next shot for the entire three-minute walk.

Use your pre-shot routine as an anchor. It’s not just for lining up a shot, it’s a bubble of calm that conserves energy. When you step behind the ball, take a deep breath. Exhale the tension. For that brief walk up to the ball, you aren't thinking, you're just executing a sequence you've done a thousand times. This mechanical process prevents over-thinking and the mental burnout that comes with it.

Winning the Battle in Your Head

Mental fatigue is just as debilitating as physical fatigue. When your brain gets tired from stress, frustration, and over-analysis, your body is quick to follow. A strong mind is an energy-efficient mind.

Let Go of Bad Shots Quickly

Grinding over a chunked iron shot or a sliced drive is like leaving your car's engine running in the driveway - it burns fuel for absolutely no reason. Emotional reactions, particularly anger and frustration, spike your cortisol levels and drain your energy reserves faster than anything else on the course.

One trick I teach my students is the "10-yard rule." You have 10 yards from where you hit the bad shot to be as angry as you want. Kick the dirt. Mutter under your breath. But once you've walked those 10 yards, it's over. The shot is in the past, and your full attention is on the next one. This simple mental trigger helps compartmentalize frustration and conserve precious mental energy.

Simplify Your On-Course Decisions

Every decision you make on the course requires mental horsepower. aggressive or safe? What's the wind doing? Can I carry that bunker? Over 18 holes, this adds up to "decision fatigue." When your brain gets tired of making complex calculations, it defaults to bad, lazy choices.

The solution is to simplify your game plan. Don't always try to play hero golf. Aim for the fat part of the green. Take an extra club and swing smooth. Choose the shot that takes double-bogey out of play, even if it means you won't make a birdie. By making the boring, high-percentage choice more often, you save your mental focus for the moments when it really counts. Smarter golf is less stressful, less tiring, and almost always leads to better scores.

Final Thoughts

Improving your golf endurance goes far beyond just your cardio fitness. It’s a complete approach that blends golf-specific strength and mobility with smart on-course fueling, deliberate pacing, and a resilient mindset that refuses to waste energy on bad shots or poor decisions. When all these pieces work together, you'll find you can close out your round with the same focus and confidence you had on the first tee.

A clear, confident decision is also an energy-efficient one. We actually developed Caddie AI to help take the mental strain out of on-course strategy.
