Wind up.
Raiz
The Raiz can be seen as many things.
1. Cheat setup darkside aerial
2. Cheat setup gainer flash
3. Gumbi Aerial
4. Inverted Tornado Kick
5. Outwards spinning butterfly kick
In this tutorial we are going to teach it from a tornado kick, which I find easiest to learn.
02 both legs straight
The next step is a tornado kick with both legs straight. No chamber. Kind of like a Cheat Feilong.
04 Spot the ground
The next step is just a small modification but it will already turn your lazyboy into a (bad) raiz. Now instead of spotting forward, like you would for a tornado kick, you'll spot over your shoulder to look for the ground. Start spotting even before you takeoff and don't take your eyes off that spot.
Changing it into a inverted (non-Side2Side) Raiz
Tips
Going from a tornado kick was definitely the easiest way for me but you can also try the other methods.
1. Cheat darkside aerial. Step into your cheat setup and do an aerial on your bad side. Spot the ground and swing your leg over. Keep your spot throughout the trick and it should work naturally.
2. The real cheat gainer. Step into your cheat setup and swing your arms as you would for a gainer flash. Swing your leg up the same way and look straight back. So basically a gainer from a cheat setup.
3. If you can already do a gumbi, you could try to turn that into a raiz, since it's a raiz with both hands. Swing your back leg hard and turn your body over fast to generate as much whip as possible, so you can leave your hands away. Swing your arms with speed and momentum.
4. Outwards butterfly kick. This is very similar to the darkside aerial technique but you'll think of a butterfly kick where you spot the ground instead. I wouldn't recommend you to use this as a primary learning method as it won't teach you how to invert properly.
