Latest thinking – I need to focus on ‘posting up’ on my left side more. Basically, by hitting into a firm left side, my lateral motion stops and the left hip rotates out of the way so the arms can get through. Also adds power because it engages ground forces more as the left leg straightens, as well as ensuring weight is shifted to front side.
Feeling is ‘snapping’ into left side at impact, left leg straightens and left hip is higher than right.
Will be trying it at the range this week, I’m sure it will take some time to get the timing right but practice swings feel good.
