[12 piece bucket]

Grab a normal sized golf towel, hold the two opposite corners together, and hit a reasonably heavy object (e.g. a half filled golf bag with legs). You learn to use your core to turn back and through. Visualise your arms as ropes, they don't contribute and muscular power whatsoever. Your hands just hold on. Tip: don't use an object where you can topple even with throwaway (e.g. a light crate like Ben sometimes uses). Also place the bag slightly in front of your left foot (i.e. forward ball position).

I have done this drill with a lot of pros, and none of them could topple the golf bag on their first go! They try harder and harder and still can't do it. It should feel effortless when done properly.

Cool! Me likey.
