I don't have enough experience to appreciate a lot of what you just said. Snatches are more of a competitive motion, and I've never even done one. At my age, I doubt I will ever do one. I only just recently started doing cleans, even.. and I struggle with getting my damn hips to push back so my posterior gets engaged and keeps it out of my lower back. So much going on with this motion. I do, however, have enough experience to appreciate when others make it look easy and just how many thousands of times they must have done it to get it to that point.
