The right arm has a huge impact on wrist angle and lag.
One of my victims has had an issue of getting the upper body in front and throwing it away forever. I told him shallowing angle of attack by getting behind it first, then his arms needed to link up.
He was a former lag holder to no avail.
Monday, on a hunch, I told him to throw the lag away on purpose. Guess what happened? His right arm sped up, linked up and produced more forward shaft lean then he has ever had. Well, wouldn’t call it shaft lean yet…how about less throw away? 😀
Notice how much better the body angles are on the picture on the right (after). Right foot hasn’t lost its leverage with the ground, right knee in more solid position, better tilt and less throw away. Notice how on the left, the right wrist is straight, while on the right, there is still angle in right wrist.
Oh, the irony. Can’t tell you how many lag holders I see actually throwing it away massively because it slows their right arm down.
