The knees are an integral yet often-overlooked part of the golf swing.

The knee of the back leg (right knee for right-handers, left knee for lefties) plays a critical role in creating a powerful, fluid motion.

The right knee, like the left, should be flexed at address. (Think of a shortstop’s stance in baseball.) From there, proper right knee action looks like this:

• On the backswing, the knee remains flexed to keep the right hip level with the left. 

• The knee is flexed yet stable at the top of the backswing. A knee bowing outward (away from the target) causes poor balance and a loss of coil – i.e. power.

• When transitioning from backswing to downswing, the right knee shifts toward the target as the right hip turns in that direction.

• At impact, the right knee should point at the target while the outside of the right foot lifts slightly off the ground.

To ingrain proper knee action, practice with a basketball between your knees. Squeeze the ball just enough to keep it in place throughout the golf swing.
