The thing that blows my mind is how people somehow NEED objective proof that one technique is superior to another. It isn't enough just to load up the bar and try both techniques? Why can't you just film both attempts and see which one looks better? Do you think competitive lifters sit around theorizing about this shit? If you're not an Oly coach or lifter, this is just all seems like mental masturbation. There are so many better things you could be doing to increase a 100 C&J than sitting on the internet arguing about a 3-5cm deviation in the start position. I mean, people do realize that competitive lifters, in any strength sport, try out an incredible amount of technique permutations before "settling" on something, right? There is no way, even with a coach, that your form isn't going to evolve over 5+ years of training.
You're right. It's just not that hard to do this. It amuses me when weightlifters refuse to try this for even a SINGLE rep, but it is even more amusing when people who aren't weightlifters, who don't compete, who don't coach, who don't ref, who don't go to meets as spectators, etc. just sit here and theorize on the fucking internet and pull random quotes of coaches they've never even met.
But, I guess that is why I bother doing it. Because I'm not a fucking moron.
Some people thought that the earth was flat. They were wrong too.
But, I bet those people have never trained with me, never coached me, never seen me coach, and probably haven't even spoken to me at a meet. Because even the Important People in Weightlifting who don't like me (which is a vastly different thing from thinking I am a fucking moron) know that I have at least bothered to do my homework.
And, most of them like me anyway since I am awesome and fun.
