Keeping hip rotation
Q: I've started hitting my wedges fat. Short shots, full shots -fat! I've tried a check list of diagnostics: tried flattening my swing, steepening by swing,weight foreward, head still, quiet lower body, active lower bory, shoulder turn, less active hands- still fat.
It sounds to me like you might be stopping your hip roatation through the hitting area, and throwing the clubhead at the ball with your hands. Try turning through more aggresively to the target and try to keep the right wrist bent back as you do that.
