My first suggestion is to learn this with a coach. You do not want to set up any bad habits that will need to be unlearned later. The prep exercises will involve back spins, waltz jumps into back spins, waltz-loop combinations, perhaps bell jumps, and something called a once-around. Full disclosure: I don't do axels. I had done the prep exercises, but kept bailing on learning the jump because of work-related fear (I'm a professional musician, and couldn't risk the falls and potential injuries coming into important performances). Now I ice dance exclusively, so I'm very unlikely to ever work on axels again.
