When I first began training in my late teens, some two or so thousand years ago, I was having serious problems getting the form down for dumbbell flyes. No matter how hard I tried, my elbows always bent into a pressing movement. One day in my early twenties, I read a passage from a book on exercise performance that instructed trainees performing flyes to "imagine the pages of a book opening." From that point on, I never had a problem.

Over the years, I became interested in the role metaphor plays in the development of the "mind-muscle connection" so many trainers advocate. Another one I often hear is squats as a rocket thrusting into the air.

Can anyone think of any other good metaphors that they've heard or which have helped them out when performing a tricky movement?
