Really? I wouldn't say this is absolutely worthless for o-lifting, but if you were coaching someone to be a good o-lifter would you really put this in their program?
Now, having said that, given this man's posting history thus far (and the fact that he's an ex-strongman, I believe) this reeks of "hey, that looks cool, wonder how much weight I can do that with." Which is fine. It's cool seeing this type of stuff (like the 2/3-ish backflip he posted as well) but I'm more interested in knowing how you're coming along with the classical lifts. I want to see more videos of you snatching and cleaning and jerking from the front (how's that squat jerk coming?).
Now if I thought that you were actually doing this as a serious part of your program thinking that this exercise was going to put kg on your classical lifts I'd call you an idiot. But I don't think that's what you're doing. It's obvious you've got some serious strength, but I know that I (and probably others here too) would like to see more of you transferring that strength to the o-lifts. After all, that's what this particular forum is supposed to be about, isn't it?
