Notice I said practice! This isn’t one for the course but here it the reason playing shots with just your leading arm on the range can benefit you on the course.

The normal golf shot is played with two hands on the club and the leading arm is kept straight through the back swing all the way to around 85% of completion of the follow through. So imagine you can hold the club with a solid grip in your leading hand (this is the one facing the target)

Keep everything as you would normally in your setup but place your back hand behind your back (see told you I wasn’t losing the plot) and using only your front arm and your body movement (which is what you should be doing through your swing) keeping that front arm straight take a swing.

OK few things I need to point out:

Make sure you take a number of practice swings

When choosing a bay on the range make sure it is a closed bay as balls have a habit of going astray with this method

Don’t try and knock the ball a long way, your natural swing will do this

Grip the club slightly more than normal with the hand you have on it, your resistance on the club is half what it normally is with two hands

Practice makes perfect.

This is one of the drills I use on the golf range when I am working on my swing, it helps improve control of the club head and pretty much forces me to use body rotation in my swing.
