A challenge

[airair]

If you should try to explain how to do a "normal" half swing (required motion) with all TGM knowledge you have - how would you explain it in the simplest terms in max one minute (without speeking very fast) to somebody who hasn't heard of TGM and its terminology?



Edited later:
To make it easier - the student doesn't have to be without knowledge of golf - only unfamilar to TGM
