I have come to learn that the 2 main oly lifts, the clean and snatch, are nearly works of art when actually perfected. I think anyone that goes in with "learn to power snatch in 3 hours" is kidding themselves.
I got the clean down pretty early on and it's definitely my best lift by far--and as such, I've made great progress with how heavy I can go. But my split jerk is still pretty lame (I get the weight locked out overhead, but my lunge is terrible), and my snatch? Forget it. I can power snatch 100lb, but if you asked me to do a full snatch with an empty women's bar (35lb), I'd fall on my ass, illustrating that strength is rarely the limiting factor in Oly lifts. They're ridiculously complicated moves and if your form isn't 100% you're not gonna land it. I liken the Oly lifts to tumbling runs in gymnastics. There's so much you have to remember and so much that has to go exactly right for you to successfully pull it off.
Give it time and practice, practice, practice. One day a certain part of the move will just click into place, and then another, and then another. But you have to practice A LOT.
