Two and a half spins around vertical axis.
How do it
A 720 plus a 180, that’s a lot of spinning to do! Some people would prefer a foam pit first.
Begin with a 540 air on a large quarter pipe, you need more air time to spin an extra 360.
Go much faster and higher and spin your 540, when you spot that you’ve spun so far, you need to again keep rotating. It’s often easier to break a spin down into steps so you can see how far you’ve rotated.
Hook the final 360 and spot your landing.
You’ll need to have good balance as you land because it takes more momentum to spin, so be prepared for landing.
