If your learning them to throw off cliffs, a way you can do it is finding a steep drop off (like a cliff, but preferably no exposed rocks) that is about 5 feet. Then you start by doing low speed, really pressed out butters off of that (the kind where you plant both hands on the ground). Keep doing those, and each time get less buttery and go in faster. You'll be able to do them in no time. I'm sorry if this explanation made no sense at all.
