TRS Slider by Robert Rock - Trail Arm Connection Golf Swing Trainer

Does your trail elbow fly away from your body? That one move is behind a lot of over-the-top slices, thin strikes and lost distance. The TRS Slider, designed by two-time DP World Tour winner Robert Rock, straps around your lower chest and holds your trail arm in a sliding strap. Your arm can still fold and move, but it can't separate from your body, so your arms and chest turn together and the club drops into the slot on the way to impact. Try it risk-free with our 60-day money-back guarantee.

Why Golfers Choose the TRS Slider

• Fix a flying elbow: the strap slides around your rib cage to a set limit, so the trail elbow can't stick out behind you halfway back.
• Stop coming over the top: if you stall your turn and throw your arms from the top, the Slider pulls on your arm and tells you right away.
• Connected, not pinned: a small gap between your arm and body lets the elbow fold and the forearm pivot naturally, unlike a towel or glove tucked under the arm.
• Tour developed: Robert Rock built it for his own swing and refined it with the tour players he coaches. Golf Monthly reports it has been adopted by more than 50 tour players, including major winner Cam Smith.
• Fits every golfer: three chest sizes, and it works for right- and left-handed players.

How the TRS Slider Works

The Slider has two loops. The black loop buckles around your lower chest, and the pink loop wraps around your trail arm just above the elbow. The arm loop rides on a track around your body, so it moves with your swing instead of locking you in place.

On the backswing, the trail elbow folds back, the forearm pivots up and your chest turns, all while the arm stays close to your side. On the downswing, your chest keeps rotating and the connected arm comes along with it, delivering the club from the inside instead of across the ball. That is the position tour players call the power slot.

How to Practice With the TRS Slider

1. Put it on: buckle the black strap snugly around your lower chest, keep it level, then slide your trail arm into the pink strap and pull it fairly tight.
2. Trail-arm-only rehearsals: with just your trail hand on the club, fold the elbow back, pivot the forearm up and add a little shoulder turn. Repeat until the motion feels automatic.
3. Practice swings: add your lead hand and make slow backswings, feeling the Slider glide around your ribs. Rock recommends doing most early practice this way.
4. Hit shots: start with wedges and a 7-iron. Hit 10 to 20 balls with the Slider on, then take it off and try to repeat the same feel.
5. Short game: wear it for chips and pitches to keep your arms and body moving together around the green.

• Players whose trail elbow flies out or gets stuck behind them
• Golfers who lose connection and throw the arms from the top
• Anyone who has tried the towel drill and found it too restrictive
• Right- and left-handed golfers of every level

TRS Slider vs. the Towel Drill

Tucking a towel or glove under your trail arm is the classic connection drill, but it pins the arm to your side, shortens your backswing and drops out the moment you lose connection. The TRS Slider keeps the same idea and removes the drawbacks.

	TRS Slider	Towel under the arm
Arm movement	Slides around your ribs to a set limit	Pinned tight to your side
Backswing	Full turn with a natural elbow fold	Short and restricted
Feedback	Every swing, start to finish	Only until it falls out
Between shots	Stays on	Re-tuck before every swing
Best use	Practice swings, irons, wedges and short game	Mostly chipping and pitching

TRS Slider FAQs

What does the TRS Slider fix?

It trains trail-arm connection. It stops the trail elbow from flying away from your body in the backswing and keeps the arms turning with the chest on the downswing, which helps golfers who slice, come over the top or strike the ball inconsistently.

What size TRS Slider do I need?

Measure around your lower chest, just under the arms. Small fits a 30" to 36" chest, Medium fits 36" to 42" and Large fits 42" to 50". If you are between sizes, size up.

Is the TRS Slider sold as a single or a set?

Each TRS Slider is sold individually. Choose your size and you will receive one Slider in that size.

Does it work for left-handed golfers?

Yes. The pink strap goes on your trail arm, so it works for right- and left-handed golfers.

How is it different from the towel drill?

A towel under the arm pins your arm to your side, shortens your backswing and falls out when you lose connection. The TRS Slider lets your arm glide around your ribs to a set limit, so you keep a full, natural turn with feedback on every swing.

Can I hit balls while wearing it?

Yes. Start with practice swings, then hit wedges and mid irons. Robert Rock suggests hitting 10 to 20 balls with it on, then taking it off to repeat the feel. With the driver, it works best for practice swings.

Can I use it for chipping and pitching?

Yes. The Slider helps keep your arms and body moving together in the short game too.

Can I wear the TRS Slider during a round?

No. It is a practice aid for the range, the practice green or at home. Use it to build the feel, then take that feel to the course.

How long until I notice a difference?

Many golfers feel a difference in their first session. For a lasting change, use it regularly in practice over a few weeks, then go back to it whenever your connection slips.

Who designed the TRS Slider?

Robert Rock, a two-time DP World Tour winner and coach, designed it after struggling with his own trail-arm movement. He then refined it with the tour players he coaches.

Is there a money-back guarantee?

Yes. InTheHoleGolf backs the TRS Slider with a 60-day money-back guarantee. Practice with it for up to 60 days, and if it isn't right for you, contact us at 1-888-733-8383 and send it back for your money back.

Does the TRS Slider ship free?

Yes. InTheHoleGolf offers free shipping on qualifying orders over $75, and the TRS Slider is priced above that threshold.
