To have a great swing, you simply need to take more swings with just your lead arm. It's that simple. The problem is, you can't do that with a regular golf club and get a realistic cadence and rhythm. It's too big and heavy. Plus, you risk injuring your shoulder. That's why I make these club available. I cut these down myself from old, used golf clubs. You could do that too, and I recommend you try if you want. But if you don't want to try, I've provided these for you to purchase.
You can actually hit balls with these. I recommend hitting off yoga blocks. You can see this video to see the Yoga Block Drill that I recommend you do with the Lead Arm Training Clubs. The reason why we sell the left and right-handed together is because you must train both sides.
