Loose elbow the key to feeling the release
Lots has been written about leading the elbow through the circle and keeping the arm loose to generate speed. But there’s another good reason to do it — high/low accuracy.
If you come through the circle with a stiff elbow, you’re going to “feel” the release being around the front leg. That will make it go high. But if you lead the elbow through the circle and keep the arm loose, you’ll feel the release closer to the back leg, and the ball will stay down.
Don’t take my word for it. Try making a circle with a stiff elbow and see where you feel your wrist snap naturally. Then loose it up and do the same. You’ll find the release point move back.
