The Flat Left Wrist is the desired mid-condition of the Wrist's Horizontal Motion ( Flat, Bent and Arched). Steering is, primarily, holding the Left Wrist in the Turned condition of its Rotational Motion (Vertical, Turned and Rolled) thereby inhibiting its proper Roll (to the Left) 'through the Ball'.

When you attempted to impose the Flat Condition in your Horizontal Motion -- remember, Homer also always said, "Willpower isn't enough" -- you unconsiously inhibited the correct Rotational Motion (which, almost certainly, was the true problem to begin with).

Lynn, do you see this a lot with students, in the attempt to keep the FLW they don't roll it through impact? I have been through that stage myself and I am coming out the other side now, but I have seen it in a lot of other golfers. Tell them to hit down on the ball with a flat left wrist and the first couple of shots are shanks or 45° open clubfaces. It seems the idea of a flat left wrist freezes people up and they don't allow it to roll over. How do you get passed that with your students?
