You will need a partner/tower for this one standing on the Down the Line camera view.

Have the partner stand at a safe distance (6-8 feet?) behind your swing and hold up a pool noodle. Have them hold up the noodle at 9 AM, directly between your hands and waist at 6 AM.  

Swing above the stick in the backswing.  After you have completed your backswing, the partner should remove the stick for your downwing.
