The Truth About the Left Arm in Golf Swing

The Truth About the Left Arm in Golf Swing

Are you one of the many golfers who worry about whether or not they should try to keep their left arm in golf swing straight?

Have you read golf magazine articles saying that all pros keep their left arm straight, and that this is the key to hitting it longer and straighter?

Miles read something similar to this as well, and wrote to us asking:

I'm fairly new to playing golf, but I have heard that I need to keep my left arm straight and that it will help me hit better shots.  Is there any truth to this - and if so - what can I do?

The answer to this question, Miles, is that it depends on the golfer.

The range of motion in your Thoracic Spine (T-spine or upper back), in almost every case, will determine how straight you can keep your left arm or how much you’ll have to bend it (for a right-handed golfer) to make a complete backswing.

For me, I do like to see golfers keep the left arm fairly straight.

I don't want it locked, but I only want this position if the golfer’s range of motion can support it.

One of the main reasons why some people are able to keep their left arm straight is because they have great range of motion in their T-Spine.

I’ve had students come to me who’ve read an article telling them that they must keep their left arm straight.

They come for a lesson, begin making a few swings, and then ask me if they were keeping their left arm straight during their swing.
