How to Square Club Face

Here we will explain what causes open club face and then provide a video explaining how to fix it.
How open club face leads to common swing faults:
1. Player keeps the club face open too long, caused by subconsciously trying to help the ball to fly up.
2. Open club face would lead to pushing the ball so the player needs to make adaptations.
3. The player is subconsciously reacting to the club face and creating common swing faults:
– Swinging to the left (out-to-in path) and thus slicing the ball
– Keeping his weight on the back foot and losing power
– Trying to square the club face at the last moment with a weak flip
Once you fix the club face, a lot of the other problems will fix themselves because they happen subconsciously as reactions to the club face.


So how to fix this open club face?

You need to understand how the club face is opened and closed. The open club face is caused by too much lead wrist extension (cupping).

Now look at the comparison of 2 swing positions:

IMAGE 1: club face is square during downswing, it is pointing in the direction of the ball – result of the lead wrist being flatter or even slightly flexed (bowed).
IMAGE 2: club face is too open, it is pointing up in the sky – result of the lead wrist being too extended (cupped).
If you have a lot of wrist extension it is impossible to consistently remove it right before impact. 

HOW THE TOUR PROS square the face

Now look at a typical tour player swing. Pay attention to the lead wrist and club face. You can see that there is little movement needed from the wrists to square the club face.

Using Hackmotion Wrist Sensor we have been measuring PGA Tour players and we consistently see that top players square the club face early by avoiding extension (cupping) of the lead wrist. They square club face early, so they don’t have to square it late.

The goal is to gradually get into a position from which you have to do less club face manipulation leading up to the impact


To learn how to consistently square the club face you need 2 things:

1. You need to know what your lead wrist is doing throughout the swing. You need DATA

2. You need a way to know when your wrist is in a good position. You need FEEDBACK

With Hackmotion Sensor you can get both data and feedback. First let’s look at the data to see how extended or flexed your wrist is and how it is behaving during the downswing.

Below is Hackmotion 3D model with European Tour player’s wrist data during downswing. The number with red circle around is extension of the lead wrist. It starts from +11 extended (cupped) at the top and gradually moves to -7 flexed (bowed) at impact.


This gradual decrease in extension is the key to face control and we typically see this among tour players. A typical amateur swing increases extension and then at last moment tries to remove it – an almost impossible task.



When you have data as reference you need feedback to guide you towards the correct solution. That is why we developed Hackmotion Biofeedback which helps you to get the correct feel for the motion.

Biofeedback is audio feedback sound which turns on when you are in the desired wrist position and turns off when you are outside that wrist position.  Watch the video below to understand how Hackmotion biofeedback works.
