Just to echo some of the other comments posted ... don't get too wrapped up in the minutia of getting your body parts into specific planes during the entire throwing motion. Focus your energies on learning good fundamentals ... a shortened x-step where you get your hips turned away from your target, accelerating your arm across your chest while driving your hips forward, and rotating completely through the entire motion so that your off-hand whips around on its own. Watch as many videos of the top pros as you can to see what good fundamentals look like. There are MANY different body types, and finding a motion that works for you is the most important thing. The key for me was just slowing everything down ... I see many casual players literally running up the tee pad, getting their balance completely out of whack, thinking faster equals farther. IT DOESN'T. I'm just walking up, rotating my body away from the target, and then accelerating back towards it. I'm balanced, slow and smooth, and equalling their throws with a distance driver with a putter.
I'll admit that my major technique flaw is accelerating and rotating too slowly or too quickly and not getting to where my release point should be to hit the flight line I want. But I know when I'm doing it, and how to correct it within a hole or two.
Good luck. It takes practice, but that first throw when you get the good snap is going to feel great.
