TRS Slider Review: Is This The Best Training Aid On The Market?

In the crowded market of golf training aids, where products often promise revolutionary results but can deliver somewhat underwhelming results, I was keen to see if the TRS Slider stands out.

Developed by European Tour winner Robert Rock, this aid is aimed at correcting one of the most common and destructive faults in the amateur swing: a flying right elbow and a disconnected right arm. I put the TRS Slider through its paces to see if this simple, ingenious device could provide a genuine solution without compromising freedom of movement.

The TRS Slider addresses the common fault of separation between the arms and body, a disconnection that leads to a loss of power, inconsistent contact, and an 'over-the-top' swing path. Its unique approach to solving this problem is what immediately caught my attention.

The beauty of the TRS Slider lies in its simplicity and subtle genius. It consists of a durable seat belt-style strap that connects the golfer’s torso to the trail elbow.

While there are a number of devices on the market that promise to achieve a similar thing, the USP here is the slider component that sits on the strap. This slider allows an appropriate range of motion during the takeaway and backswing, whereas many aids attempting the same are simply too restrictive, forcing an artificial, and potentially damaging swing motion. The TRS Slider prevents the trail elbow from flying away from the body without locking it in place.

This concept is rooted in the practical experience of professional golf. Having spoken with the man himself, I know that Robert Rock actually fully prototyped this himself originally using seat belt material and clips that he had sourced from eBay! This homegrown, trial-and-error approach gives the product real authenticity - it’s a solution a professional devised for his own game, not just a gadget dreamed up in a boardroom.

On the range, the impact of the Slider was immediate. It provided instant feedback, letting me feel exactly when my trail elbow strayed too far from my body line in the takeaway, a common cause of steepening the shaft. The feeling is one of connectedness; it teaches the body and arms to work as a unified piece, facilitating a much better structure to the takeaway and backswing.

Unlike rigid aids, the TRS Slider allows the arms to fold naturally at the top, preventing the feeling of being constricted. This focus on allowing appropriate movement, rather than violently stopping it, is what makes the training so effective and transferable to the actual swing. After hitting just a few balls, the feeling of the arms staying "in front" of the chest becomes ingrained.

The TRS Slider is not just another novelty; it is a genuinely innovative and unique way to control the right arm function in the swing. For golfers struggling with a flying right elbow, a disconnected takeaway, or inconsistent structure at the top, this device offers instant feedback and a clear path to a more compact, powerful, and repeatable motion.
