Cheat 720
TKT: Cheat 540 Hook. The Cheat 720 is an 360 degree spin from the cheat setup, ending with a hook or crescent kick. You can also get away with a little bit less rotation, since the hook kick adds to the rotation on the ground.
Two different Cheat 720 Kicks
Single pump
The single pump is the easier version of the two. You just raise one knee up, spin once while keeping it up and then kick.
They both have their own progression line, so I recommend you to learn both.
Single Pump
01 Tornado
Start off with good and floaty tornado kicks. They will teach you how to use your knee to get height. Swing your arms wide around and up to get even more lift.
02 360 degree spin
Now use the tornado setup for a 360 degree spin. Just do the setup, raise up your knee and spin once. Try to stay as upright as possible, so you won't lose balance when you land.
Double Pump
02 Tsunami
The Tsunami, or stepover hook kick, is very important when you want to learn the double pump variation. Pull your knee over and turn around fast to fire the hook kick. This will teach you the exact motion you need.
03 Fuse them
Now put it together. Setup for a big tornado kick. As you swing up your first leg, jump off and tsunami over the other leg. That means pull your non kicking leg over the other leg. Rotate your hip with the pump. Use your arms to get more lift. Spot early over your shoulder and release the kick. ....Or just do a tornado and cancel it into a tsunami.
Tips
The 540 Kick can also help a lot for the double pump variation. You could think of it as a 540 with a bent kicking leg, into a hook kick.
Swing your arms wide before your takeoff and then bring them into your body for a fast spin.
If you are falling forwards or backwards when you land, you are most likely spinning off axis. Try to stay as vertical as possible. Practice the second step of the single pump tutorial.
Practice your tsunamis and your Cheat 720 double pump will improve at the same time.
