Locking Your Right Knee

Golf Swing Error – Illustrated Guide

As the name of the golf swing error implies, locking up the back knee involves gradually straightening the right leg during the backswing. At the top of the swing, the error is clearly visible through a right leg that is completely straight, with no knee flex to be found.

This is in contrast to a better swing that sees the flex in the right knee maintained more or less throughout the swing. Indeed, at address both knees are set in an athletic position using a reasonable amount of flex. That flex is to be kept throughout most of the swing until impact is made with the ball.

Problems Associated with Locking up your Right Knee

Changes the Angle in your Hips – Leads to Inside-Out Club Path

Locking the right knee leads to an inside out swingThe main issue with losing the flex in your right knee during the backswing and at the top of the swing is that it changes the angle and direction in your hips.

Indeed, whereas the hips are supposed to coil and uncoil along a central axis without moving much sideways, the act of straightening the right leg will pull your hips towards your right leg. In doing so, it will also open up your hips to the right side.

From that point on, it will be difficult to bring the club towards impact in anything but an inside-out swing and club path. And while that club path is not completely undesirable in itself, it does render hitting straight shots at the target very difficult.

How to Stop Locking up your Right Knee

Set the Proper Knee Flex at Address

Knee flex should feel right; Not too low and not standing too tallThe first step you need to take in order to solve this swing error is to make sure the knee flex you create at address is proper and correct. Setting up incorrectly during the setup can lead you to modify the right knee flex as a way to correct this initial setup position flaw.

In order to do so, make sure to bend your knees slightly. You will want to avoid bending your knees too much and you definitely want to avoid seeing your legs fully extended.

Rather, make sure that your knees provide a good mid-point and will allow you to perform your swing with ease without needing the change the angle in your legs.

Imagine your Right Knee is Tied to the Ball (or the Tee)

Imagine your right knee is tied to the ball with a string; don't pull that string during your backswingHere is a good mental image that you can use in order stop locking your right knee during your backswing.

Imagine that your right knee is attached to the ball (or to the tee under) with a piece of string. Imagine that this string has tension when you set up to the ball.

Now imagine that pulling on that string during the backswing – by locking your right knee and moving away from the ball – will break the string or pull the ball or the tee out of its initial position. 

Focus on keeping the flex in your right knee in such a way that you would not be breaking the string.

Lean in Your Right Knee

Lean in the right knee to help fix locking the right kneeThere is another trick that helps set the right knee in its place and that is to lean in your right knee at address.

As a useful swing trigger, the act of leaning your right knee towards the inside (towards the left knee) brings the knee flex – and the location of that knee – into your subconscious.

As a swing trigger, it cements that position since it is the last movement made while setting up for a shot before the takeaway can proceed. It helps in preventing the knee from moving laterally and it also helps in setting and keeping the angle of the knee, which is what is being sought here.
