The 30-Second Move That Prevents ‘Sim Elbow’ During Indoor Golf Sessions
The landscape of the game has shifted dramatically over the last few years. While the traditional driving range still holds its place in the sun, the “indoor golf boom” has transformed how we practice. With the convenience of finding a golf simulator near me or booking a high-tech trackman golf session, golfers are no longer at the mercy of the seasons. We can now grind out swing changes in January, wearing a t-shirt, while a blizzard rages outside. However, this accessibility has brought a specific, nagging injury to the forefront of my clinical practice: “Sim Elbow.”
As a Board Certified Sports Physical Therapy Specialist and a TPI-certified instructor, I’ve seen a massive uptick in golfers presenting with medial epicondylitis – commonly known as Golfer’s Elbow – specifically after transitioning to indoor golf. They aren’t hitting off lush turf; they are hitting off synthetic mats. While the golf simulator provides incredible data, it also provides a much harsher impact on the human body. If you’ve started feeling that sharp, localized ache on the inside of your lead or trail elbow after a session at the indoor golf simulators, you aren’t alone. But more importantly, you don’t have to stop playing. There is a specific, 30-second physiological “reset” that can save your season.
What Exactly is “Sim Elbow”? (And Why Mats are Different Than Grass)
To understand why your elbow is screaming, we have to look at the physics of the impact. In a traditional outdoor setting at a driving range near me with natural grass, the clubhead interacts with the soil. When you strike the ball, the club compresses the turf, moves through the dirt, and creates a divot. This process allows for a gradual dissipation of energy. The ground “gives,” which means the shock of the impact is absorbed largely by the earth.
Now, let’s look at the golf sim environment. Even the highest-end mats at luxury indoor golf simulators near me are essentially a layer of synthetic fiber over a concrete or wooden subfloor. When the club strikes this surface, the “Ground Reaction Force” (GRF) is significantly higher. Research suggests that hitting off a mat can increase the vibration and shock transmitted to the forearm by up to 50% compared to hitting off lush turf. Because the mat doesn’t “give,” that energy has to go somewhere. It travels directly up the shaft, through the grip, and into the soft tissues of the wrist and elbow.
This repetitive high-impact loading leads to micro-trauma in the common flexor tendon. Over time, the body’s ability to repair this tissue is outpaced by the frequency of the indoor golf sessions. This is how “Sim Elbow” is born. If you want to dive deeper into the recovery side of this condition, check out The Secret to Recovering From Golfer’s Elbow Fast. But before we talk about recovery, let’s talk about the proactive move that prevents the injury from taking hold in the first place.
The 30-Second Move: The Eccentric Wrist Flexor Reset
If you are standing in an indoor golf bay, waiting for the trackman golf software to load the next hole at Pebble Beach, you have enough time to save your tendons. The “Secret Sauce” to preventing Sim Elbow isn’t just a simple stretch; it’s an eccentric loading reset. Most golfers make the mistake of only doing passive stretching, which does little to prepare the tendon for high-velocity impact. We need to build “tensile resilience.”
Step 1: The Setup
Extend your arm (the one experiencing the ache, or both for prevention) straight out in front of you at shoulder height. Turn your hand so your palm is facing up toward the ceiling. Keep your elbow completely locked out; if the elbow is bent, you aren’t isolating the tendon correctly.
Step 2: The Passive Stretch
Use your opposite hand to grasp the fingers of the extended hand. Gently pull your fingers and palm back toward the floor. You should feel a significant stretch along the underside of your forearm, running from the wrist toward the inside of the elbow. Hold this for 5 seconds to “quiet” the nervous system.
Step 3: The Eccentric Reset (The Secret Sauce)
While maintaining the stretched position, try to “curl” your wrist upward (as if making a fist and bringing it toward your bicep). Crucially, do not let your wrist actually move. Use your opposite hand to provide enough resistance that your wrist stays in that extended, stretched position. Hold this isometric contraction for 5 seconds. Then, very slowly – over a count of 5 – allow the opposite hand to win, pushing your wrist back into the deep stretch while you continue to provide resistance.
This “eccentric” phase (where the muscle is lengthening while under tension) is the most important part. It stimulates the collagen fibers within the tendon to realign and strengthens the tendon’s ability to handle the “shock” of hitting a hard mat. Doing this for 30 seconds (3 reps of 10 seconds) between every 20-30 balls can effectively neutralize the cumulative trauma of a golf simulator session.
Why Your Trackman Metrics Might Be Predicting Injury
As a TPI-certified professional, I love data. When you go for golf lessons near me and use a trackman golf system, you get instant feedback on your swing. However, these metrics aren’t just for lowering your handicap; they are early warning signs for your physical health. Specifically, I look at “Angle of Attack.”
If your Trackman data shows a very “steep” attack angle (e.g., -6 to -8 degrees with an iron), you are essentially driving the clubhead directly into the floor. On grass, this results in a deep divot. On a golf sim mat, this results in a violent collision. The steeper the angle, the higher the Ground Reaction Force, and the faster you will develop Sim Elbow.
If you notice your elbow starts to throb after a session where you were focused on “pinching” the ball or hitting it “pure,” your swing mechanics might be the culprit. A steep attack angle combined with the lack of “give” in synthetic mats is a recipe for medical epicondylitis.

Beyond the Elbow: The Role of Grip Strength and Shoulder Mobility
In the world of sports physical therapy, we often say that the site of the pain is rarely the source of the problem. The elbow is a “hinge” joint caught between the wrist and the shoulder. If either of those joints isn’t doing its job, the elbow pays the price. This is especially true during indoor golf where the repetition is higher than a standard round of golf.
First, let’s talk about the “death grip.” Many amateur golfers, when hitting in indoor golf simulators, subconsciously grip the club tighter because they are hitting in a confined space or trying to “swing hard” to impress the launch monitor. A tight grip pre-tenses the forearm muscles. When the club hits the mat, those pre-tensed muscles can’t absorb any vibration, so the force goes straight to the tendon bone interface. I discuss this in detail in Why Your Elbow Pain Is Actually a Grip Strength Problem.
Second, we have to look at shoulder mobility. If your lead shoulder (the left shoulder for a right-handed golfer) lacks external rotation or proper scapular stability, your body will compensate by overusing the forearm and wrist to square the clubface. This “flippy” motion at the bottom of the swing increases the likelihood of a “fat” shot on the mat, which is the primary catalyst for Sim Elbow. You can test your own readiness for the golf sim by following this guide: How to check your own shoulder mobility in 30 seconds.
Creating a “Sim-Safe” Warm-Up Routine
Most golfers walk into a golf simulator near me, drop their bag, and immediately pull out the driver to see how far they can hit it on the virtual driving range. This is the fastest way to end up in my clinic. To prevent Sim Elbow and general stiffness, you need a routine specifically designed for the high-impact nature of indoor golf simulators.
1. The 30-Second Eccentric Reset: Perform the move described above before you even pick up a club. This “wakes up” the tendons and prepares them for loading.
2. Thoracic Rotations: Spend 60 seconds doing “Open Books” or standing thoracic turns. If your mid-back is stiff, you will compensate with your arms, leading to more “fat” shots on the mat.
3. Progressive Loading: This is the golden rule of indoor golf. Start with your most lofted wedge. Take 50% swings for 10 balls. Move to a 7-iron for 75% swings. Only after 15-20 minutes of progressive loading should you reach for the woods. This allows the joint fluid to warm up and the tendons to adapt to the impact forces of the mat.
Indoor practice is a double-edged sword. It allows for incredible skill development, but the lack of “walking time” between shots means you are hitting 3-4 times more balls per hour than you would on a course. Without a proper warm-up, you’re asking for trouble.

Conclusion & Call to Action
The rise of the golf simulator is one of the best things to happen to the game, allowing us to stay sharp year-round. But we cannot treat the indoor golf environment the same way we treat a lush grass fairway. The increased ground reaction forces from synthetic mats require a more proactive approach to injury prevention.
By implementing the 30-second Eccentric Wrist Flexor Reset and paying attention to your trackman golf metrics, you can enjoy the benefits of high-tech practice without the chronic pain of Sim Elbow. Remember, pain is a signal that your “Body-Swing Connection” is out of sync. If you find that this 30-second move provides temporary relief but the pain keeps returning, it’s time for a professional assessment.
