The Training Aid Robert Rock Built For Tour Pros Has Quietly Taken Over The Range – We Take A Closer Look

Robert Rock has one of the most technically sound swings in golf - a fact even his peers stop to acknowledge.

Since stepping back from tour, Rock has turned his attention to coaching, and prototyped a new training aid with some of his DP World Tour clients.

But the TRS Slider is not just proving popular on the professional circuits; it’s quickly becoming an extremely popular training aid with amateur golfers, too…

The most important position in the golf swing

After years on tour and many hours analysing the golf swing, Rock developed a clear view of what separates good ball strikers from the rest.

Every golfer swings it differently. But every golfer needs to deliver the club from the same place — what tour players call 'The Power Slot'.

The Power Slot is just before impact, with the trail arm tucked close to the body, approaching from the inside, driving through impact.

If you can find the right position, everything improves: more compression, better ball flight, better accuracy, a more consistent path and, for most golfers, the removal of the dreaded slice. It’s the key to a successful and repeatable golf swing.

However, knowing about the power slot and finding it mid-swing are two very different things. Consistently reaching the power slot is not something that can be ingrained in a week.

The idea for the TRS Slider came from a simple thought from Rock: ‘What if any golfer could arrive in the power slot automatically – from their very first swing – without years on the range or thousands of pounds in coaching?’

What the TRS Slider does

The TRS Slider uses a loop around the bicep of the trail arm and a second loop around the chest, with a small gap between the arm and the body, allowing the arm to slide around the chest through the swing.

It’s a subtle but significant upgrade on the traditional towel or glove-under-the-arm drill. Unlike those methods, the Slider still allows the trail arm to move freely around the body in a natural swing motion. Keeping the trail arm connected but not locked in is the key distinction.

In the backswing, this connection prevents the trail arm from separating. This is the movement that lays the foundation for a poor impact position in most amateur swings.

You can make completely normal swings with the Slider on. The difference is that your club is automatically delivered into the power slot.

On the downswing, because the trail arm stays connected, the body and arms are guided to move in sync. The result is an in-to-out swing path – which means no slice – hitting the power slot.

In most cases, this produces a straighter and longer ball flight – all of this without having to think, or groove the pattern over thousands of repetitions.

GM’s Joe Ferguson recently reviewed the TRS Slider and offered high praise when considering its effectiveness.

“The TRS Slider is a genuinely innovative and highly effective training aid. It uniquely achieves its goal of controlling the right arm function by promoting necessary movement rather than simply restricting it.

“Its comfort and ability to teach connection make it an invaluable tool for golfers struggling with takeaway flaws and a flying elbow. It’s an authentic, tour-developed solution that quickly translates into a more stable, powerful swing.”

Trusted From Tour To The Local Range

Built by a tour professional and refined on DP World Tour ranges, the TRS Slider has been adopted by more than 50 tour players, including Major winner Cam Smith.

Short game coach Dan Grieve has also endorsed it, recognising the same connected arm position applies just as critically to shots around the green.

But it's getting rave reviews from everyday golfers too. A few comments on social posts below:
