One of the most common set up mistakes I see people make every single day. Both in person lessons and online, is having too much knee flex. And a lot of it comes from not understanding, when we're talking about setting up your weight through your ankles. That just by doing that, you don't need to then squat down. Because watch what happens to my upper body, my spine angle, as I start to add too much knee flex.
So, let's just say, I'm going through my set up routine. Hinging forward and then adding a little bit of knee flex, very little knee flex. As I start to add too much, notice that my spine angle begins to change. And that's what happens all the time as golfers start to try to get set up and feel really stable and balanced over their ankles, they add too much knee flex. And now, all of the sudden their spine is setting themselves up in position where they have to swing very shallow and into out.
So especially, if you struggle with hooks or blocks are coming too far from the inside, hitting it off the hozzle, hitting it too close to the heel. The first thing you need to check is your knee flex. The more you flex, the more upright your spine is going to be. And as you know, I've talked about it ton. Your spine angle is one of the primary dictators of swing plane. So, you need to make sure that your upper body is tilted forward, your buttons are your shirt are pointing down at the ground. And then just relax your knees slightly, and your weight is still over your ankles. But, you don't have all this added knee flex that puts you in position where you have to swing into out.
So, let's take a look. I'll hit a couple here and I'll show you, just little nine to three swings. And I'm going to stand with a lot of knee flex. And I'm going to show you what happened. Notice how my hands get lowered. This is perfect for a bunker shot, but not great for a full swing. Now that my spine is pretty upright, as I go back, the tendency is going to be for me to swing way into out. And launch the ball to the right.
To fix the swing plane, we have to first set our spine angle correctly in the first place. Which means feeling much more hinged forward, than I ever see most amateur golfers. Almost everybody tends to set up like this. You've got to get comfortable being bent forward more, your hips back more. And then your weight is over your ankles with relatively very little knee flex. And now my spine angle is set in a position where my swing plane can come down more on top of the ball. And drive the ball down the line. Instead of out to the right.
So, when you're adding knee flex, the trick is as you're hinging forward and going through your set up routine, that I talk about in the set up videos. Just barely relax the knees. Try to stay relatively tall through your lower body and hinge more from your hip sockets. So that your belt line angles down. That's going to allow my spine to stay in neutral and allow me to create a much better swing plane. Then if I'm standing up very upright with a lot of knee flex.
