Learn Correct Wrist Mechanics using HackMotion

The key to consistent swing is getting the clubface into a good position before it gains speed.

Look at PGA Tour rising star Sungjae Im – first move starting his downswing, he is twisting the clubface shut using his hands.

Once you get into a bad position during transition, it is impossible to recover.

Amateurs have been sold a lie – they think they will add more distance if they hinge their wrists to get more lag. But actually it is the opposite.

Look how the player below lifts hands, cups the wrists and the pulls on the handle during transition – he gets into a position he can not recover from and can not rotate his body. This is obviously extreme case, but to lesser extent it happens very often.

Bad Example:

Extreme wrist hinging and pulling, open clubface, losing speed

Good Example: Tommy Fleetwood

Once the clubface is in a good position, you are are able to rotate the body.

Wrong wrist and hand motion gets players into a terrible position:

  1. The more they hinge wrists and pull on the club
  2. The more they open the clubface and get the club too much in front of them.
  3. Then they have to stall the pivot to square clubface, by flipping their hands before impact

So they actually lose speed and distance because they can not rotate the body.

Tour players like Tommy Fleetwood are able to generate speed with their bodies, because they get the clubface in a good starting position, not too open.

Early squaring of the clubface, stable wrist mechanics create consistency.

Look how Tommy Fleetwood squares the club face early – it points down and towards the target. He gets the clubface behind him, so he can rotate his body

Now, look how the player struggling with slice (like most amateurs) has his clubface wide open and pointed to the right. The only way he can hit the ball is move swing path left, and the out-to-in club path creates massive side spin and a weak slice.

The key – Wrist Extension & Flexion (Cupping & Bowing) controls the clubface.

Extension(UP) / Flexion(DOWN)

Extension (cupping) opens the clubface, Flexion (bowing) closes the clubface

Tour players are experts in controlling their wrist angles and the clubface

Look at the green line below – this is wrist data of a typical tour player measured using HackMotion Wrist sensor. After top of the backswing the green line goes downwards – the player is flexing (bowing) his lead wrist.


Amateurs have unstable wrist mechanics and struggle with clubface control

Now look at the solid green line below – that is a typical amateur wrist motion. The red circle highlights the area which is the biggest issue – the large amount of wrist extension (cupping) the player gains in transition.

The tour player’s dotted graph line goes downwards right after the top – wrists move towards flexion and the clubface gets being squared early.

How to train club face control with HackMotion

Here is a simple way to analyze and improve your club face control using HackMotion:

  1. BASELINE – Take 10 swings with HackMotion and look at your extension/flexion line pattern of your good swings and bad swings. Are you having repeatable and stable flexion/extension every time?
  2. MAKE IMPROVEMENT – Change to a more stable flexion/extension pattern at the top and transition, similar to tour players. Square the clubface to target early in the downswing, so you don’t have to do it late.
  3. PRACTICE REGULARLY – Use HackMotion sensor to monitor the progress, compare you bad swings vs good swings and get accurate data after each swing. Clubface is king when it comes to consistency, so make clubface control key to your game.
