I think it was a combination of a few things:Nice! Why do you think you jump forward? Starting your pull when the bar's still on your thigh or not pulling it "back" enough?
* Jumping too high - not quite a donkey kick, but still bad.
* Not leaning back enough on the 2nd pull.
* Not keeping the bar close enough to the body.
He had me draw a chalk line on the ground, set my feet up against it and make sure that at the end of each rep, I had not jumped over the line. It worked pretty quickly to resolve that issue.
As for the jerkiness, it's understandable since you're so strong overall that you're probably thinking "alright, here we go!" - but I don't know what to suggest other than what you're probably already doing - 3-position snatches combined with "slow, slow, QUICK!".
Yea, this one is probably a mental issue and I wasn't aware of it at all. I should probably record myself while doing the snatch and do a bunch of reps until I can "feel" what a smooth rep feels like vs. a hitched rep.
