Do you have trouble getting effortless power through the ball?
If so, you may have overlooked the role of golf forearm rotation during the takeaway, a key to achieving a powerful release.
I'm sure you understand that counter-clockwise rotation (for righties) must happen in the downswing.
However, you MUST get in the proper position in the backswing to prepare for it by rotating the forearms during the takeaway.
Many golfers don't.
But fear not, there's good news:
It can be much easier than you might've thought to correct the position you see below.
Forearm rotation is incredibly important in the golf swing. It's going to allow you to set the golf club on plane during the backswing, and it's also going to allow you to release the club effectively and pick up some club head speed with very little effort.
The first thing we need to understand about golf swing forearm rotation is that, as the club goes back, the forearms are going to rotate about 45 degrees. As I mentioned, this sets the club on plane.
As we come down we're going to need to release this rotation, and that's what's going to increase club head speed. Imagine, if you take this club right out in front of your body and you rotate your arms 45 degrees, that's essentially what's happening during the backswing.
To further understand how this actually works, I want you to grab your right wrist. You'll feel this bony protrusion at the bottom of your right wrist here. This is your ulna. This is the bone that's on the outside of your forearm; your radius is on the inside of the forearm.
You can feel, as you twist these back and forth that these rotate on top of each other, one way or another way, and that's what helps the forearms rotate in the golf swing. As I'm doing this, you'll notice my upper arm is not rotating. My forearm can rotate independently.
Your upper arms also have a job to play in this rotation, especially the left arm. My left elbow here, and my upper arm, is going to rotate a bit internally to help set that club on plane during the backswing. That's what's going to help rotate the arm.
My right arm, on the other hand, pretty much the upper arm is going to be fully externally rotated, leaving this elbow pit facing toward the sky, as we've mentioned several times before, in other videos. This elbow pit is going to be externally rotated, and it's going to be pointing straight up.
Most of the right arm rotation in the golf backswing is going to happen just from the wrist, and the radius and the ulna, as we talked about before.
The tip for today is a great checkpoint, and a very easy visualization to have. It's to do with the right thumbnail. As we go back to the completion of the takeaway, a couple of things need to happen. One, the face needs to be vertical.
This face needs to be rotating until the completion of your takeaway. That face is vertical on the club. If I do this correctly, if I have a neutral grip, my right thumbnail is going to be facing straight up toward the sky.
Let me do this again for you, in slow motion. As I turn back, I'm really focusing on this right shoulder turning back. I'm getting a little bit of forearm rotation so that my club head is vertical, and now the nail of my right thumb is facing straight up toward the sky.
If I don't get enough rotation of the golf club during the takeaway, the club is going to be shut, as I see almost every day in the swing reviews - pretty much every day - and this thumbnail is now going to be pointed over in front of my body.
One of the reasons this all came about was, a lot of golf instructors tell you to swing the club where, at the completion of the takeaway, the club face matches your spine angle. This simply isn't true. If I went by this ideology, the club face would match my spine the entire swing, and I think we can all agree that this is...I'm not even sure if that's possible, but definitely not the ideal position to be in. We need this face to rotate open, and then closed, so that we can pick up some club head speed.
One last thing that this right thumbnail is going to do for you; it's going to make sure that you don't cock the wrist too early. If my club gets to parallel, and my right thumbnail is pointing vertically, I can't cock my wrist or the thumbnail would be pointing back towards me. If I cock my wrist too early, now my thumbnail is out of position.
If I do it correctly, my hands are a bit below my waist, I'm at the completion of the takeaway, and my right thumbnail straight up toward the sky. This is how much forearm rotation is needed during the takeaway in the golf swing.
I will mention that this is a drill, the exact degrees of rotation of your thumbnail may not be perfectly vertical at the completion of the takeaway. The goal is to get the club face vertical, so if your thumbnail is a couple degrees in or out, it may not be absolutely perfect.
If we have a neutral grip, it's going to be pretty close. If you have a very strong grip, so if your hands are turned to the side, your thumbnail may be pointing a bit to the right. If you have a very weak grip, your thumbnail may point a bit to the left.
Another recommendation would be to try to work toward a neutral grip, and then realize for this drill the exact degrees of rotation of the thumbnail may not be perfect.
I saw such an improvement in my golf swing by being a free member that I wanted the full benefits of a premium membership. I'm a notorious range rat who has learned more with my premium membership than I have from thousands of dollars of lessons and training aids over the past 20 years.
Excellent, thorough, detailed and comprehensive free information had me wanting more and the price/value was excellent.
The swing instruction offered by the free version made it apparent that this is the right way to perfect the golf swing (or get as close as possible). Just a few videos on how to start the backswing and initiate the downswing made a huge difference in my consistency.
After watching the free videos, I quickly realized the golf action Chuck is teaching is based on common sense fundamentals that most tour professionals use today. I also realized Chuck had a talent for explaining the golf swing in a way that makes sense.
