anylization of a jacknife

[maxx]

Ok i pose the question..is a 540 hook..really a 540 hook?

I ask this, cause i was analyzing on how to do a jacknife. slowing down videos...trying to figure out what i can do to help. And i was realizing that...its not really a 540. I'm using rudy as an example since people say he has a good one. How is this a 540...normally on a 540 you kick over the knee. But in a jacknife the kicking leg comes up about i'd say half way..maybe even less then you turn for the hook. Is it still a 540? or is more of a cheat-540?

Good jackknife has a 540, standard jackknife doesn't reeeeally have much of a first kick.

i always heard that rudy has a good one..is it cause its fast people don't realize this? i mean i slowed it down to try and figure it out.

I noticed most people kick low for the 540, then high for the Hook. I have no plan on doing this move, but I love the way it looks, so I've watched all the vids I can in slow mo and regualr speed, and thats one of the things I've noticed. And yes, Rudy doesn't kick the full 540 I don't think. He even says if you kick lower for the 540, than the hook will come out clean. Chris Devera has a good one, I saw a gif of his once, but I didn't analyze it. Maybe he does the same thing, I'll look for it and post back.

Look at Manny Brown's jackknife, in his second bilang sampler. I think it's up right now.

It's a strange move to perform, as I don't even remotely think 540, but I think more on the lines of Cheat720twist and a strange raiz.

I think about laying back after bringing that leg up, and then forcing my back leg and my hips over, and then the final hooks comes out. Barf. I only had this move for a week or so, now I can't fully mentally throw the motion when I do it. I need to conditon my mind for this move again. The movement is so smooth.

ok i just checked out mannys he does a real 540, and damn...but when he hooked his foot was technically on the ground. his was more of the jacknife i expect to see. like when he started the hook he was mid air but when he was half way complete he was on the ground.

i remember devera says he does a layed back version cause he feels its easier to hook it....i think thats wut he said.

Yes well look at Chris D's jacknife then haha, especially the one Gdong posted.
And yea, most people just dont really see that Rudy doesnt do much of a first kick, in any footage we see anyway.

Sometimes the line is blurry between a pumpy 540 crecent and a jacknife. There was a clip in chris mark's sampler that made me think of that; it looked like he was going for a jacknife but if you looked closely there really wasn't a first kick. A lot of people kind of extend the first leg then drop it to throw the hook. Manny Brown and Ben Brown have some pretty solid kicks though.

i think mark was doing a crowdawakener hook.

That's not what I'm talking about, I'm referring to the clip at the beach.

I think it should be done with both kicks. Full extension.

good example..fs md sam

both full extensions, a good way to tell is if you pause his jack on the first kick, it looks just like a 540 would.

[FDD]

pretty much the deal is that you can't follow thru with your first kick on the jacknife without messing up your hip positioning for the second hook

even the people that do a nice kick, they only have full extension in the front, and have to stop it near the middle so that they can throw out the hook.

if you do follow thru with the kick, you have to over rotate and kinda do a crescent out, but then you also tend to land as your throwing the crescent out.

so basically, ppl don't kick all the way up because they're not allowed to follow thru, so its just a lot easier to lift it there without kicking, its possible to have a full extension kick like devera, its just complicated because you can't follow thru

A jack knife should have at least two kicks. Rudy can throw some nice jack knives, but I checked his maslinc how-to myself and he doesn't do it the way he sometimes does it. People like it because it's fast and he has really good extension on the last one.

What specifically are you having troubles on with your jack knife?

i don't have one yet...i was trying to figure out what i should be doing. I'm realizing i can cheat it for beginner, but i wanna be able to eventually go full extension.
