Over the last couple of weeks, a lot of coaches have asked me what training aid I actually use in my coaching. The short answer is simple: bands. Most of my players already know that.

The obvious reason is cost.

Most training aids cost over €100. Many players can’t justify that, especially if the aid only gets used for a few weeks while working on one specific feel. Bands are cheap, flexible, and can be used in lots of ways.

There’s also technology-based training. Many players already have access to it. The issue isn’t availability, it’s overload. When players read blogs or watch content around these systems, they often get confused by the amount of data presented. They’re told they need to be in certain positions or within specific numbers because that’s how good players move. The problem is those ranges aren’t always relevant to the player in front of you. Instead of creating clarity, the data often creates noise.

That got me thinking more about feel versus real.

Feel versus real

Here’s a recent example.

A player came in with too much forward bend at setup. That pushed pressure into his toes and left him off balance. We worked on getting him closer to neutral. There was no training aid for this. He had to be aware of what he was doing and use his phone to record his setup.

He came back the following Friday and his posture had gone the other way. He was now too upright.

He went from one extreme to the other.

That’s feel versus real.

Another example:

• A player swayed towards the target in the downswing
• Contact suffered
• We placed an alignment stick outside the lead hip
• The task was to avoid touching it at impact

That feedback works, but it still relies on external reference. It also isn’t as easy to set up or repeat consistently as people think.

These sessions raised a bigger question.

What’s affordable and useful long term?

I started asking myself:

• How do we give players feedback without overload?
• How do we make it relevant to the individual?
• How do we avoid buying separate tools for separate issues?

That’s what led me to the idea of building an app.

The app concept

The concept is simple.

• Two sensors
• One on the upper back
• One on the pelvis

The app provides automatic audio feedback when the player moves outside predefined ranges.

Players can set ranges for and many more:

• Forward bend
• Side bend
• Sway
• Rotations
• General pivot control movements

The target price is €100–€150, or €45 per month to rent.

Why this app is easier to use

This app is designed to work with a coach, while still giving you the option to train on your own.

It’s a biofeedback tool by design.

Most golfers don’t really know what they should be working on. They rely on quick tips or generic technology feedback, which often misses the real issue. A coach understands what you need based on experience and observation, not just numbers.

This is where the app becomes valuable.

You leave the lesson with a clear goal and a way to train it properly. The ranges are set during the session, and the feedback you get is directly linked to what you worked on with your coach.

There’s also a practical benefit:

• Sensors sit under your clothing
• No visible training aid on the range
• Feedback goes straight to your phone
• You can use headphones for audio feedback

You can practise without worrying about setup, attention, or guessing. You get immediate feedback and stay focused on the task set in the lesson.

Taking the feedback onto the course

The value of this app isn’t limited to the range. It also allows you to take the work onto the course.

For example, imagine you’re on a par 4 and your tendency is to sway away from the ball. That movement shifts low point and affects contact. With the app running, you can see if you’re actually applying the skill on the course, not just during practice.

You get instant feedback in a real playing environment. That’s where change really matters.

It closes the gap between practice and play, and shows you if the work you’ve done in lessons and on the range is holding up under pressure.

Why this works better than a single-purpose training aid

Most players don’t struggle with one isolated issue. They struggle with movement patterns, especially pivot control.

Take the player with too much forward bend:

• We set posture ranges specific to that player
• The app gives feedback the moment they leave that range

If they sway off the ball too much, they hear it.

If posture changes during slow practice swings, they hear it.

This is where feel versus real becomes clear.

What you feel is often not what you’re doing. Instant feedback closes that gap.

The real value

This type of training aid isn’t about feeding players more data. It’s about boundaries.

• You know the range you need to stay within
• You get feedback immediately when you leave it
• You can train slowly and accurately

That’s far more effective than buying something for one issue, using it briefly, then moving on.

Final thought

This is a challenge a lot of coaches face. Players want feedback, but it has to be clear, relevant, and affordable.

Over the coming weeks, I’ll talk more about this idea. But the key question remains:

Does it bring value to the player?

For the coaches I’ve spoken to, the answer is yes, when feedback is built around individual ranges, not generic numbers.
