Firstly, one must understand that a ‘Shank’ means that you strike the ball ‘On The Hozel’ and not on the ‘Sweet Spot’ or relatively ‘Center Of Face’. This is a physical or mechanical reality. It is both annoying, quite unnecessary and easily understood. Be intellectual about this error!
If you are an ‘Arms Over Legs’ (deficient ‘Clubhead Lag Pressure’ … hands leading the Lower Body Machine (LBM) rather than trailing, you may find yourself ‘Reaching For The Ball’ with an ‘Above Plane and Path Error’. This can expose or present the ‘Hozel and not the ‘Center Of Mass’ to the Ballistic Point of the Ball. (BIC) Oops!
