Tornado kicks and pop rounds are the start of a 900, because they have the same components: a takeoff into a (small) spin landing with a round kick. In the Novice 9s video you can learn to upgrade these Basic (180°) jump round tricks to double the in-air spin. This video covers the most important tactics for adding rotation without compromising control, and it highlights how to maintain your balance while spinning vertically from pop, cheat, or swing takeoff.
Do a Tornado Kick, add another spin. A simple concept, but not realistic in practice. The only way to guarantee you'll pull off your 900s at higher in-air spins such as 540° is to ensure you can still control your balance while airborne. This video teaches you to apply the techniques from the Novice 9s video in more advanced rotations, from pop (Backside 900), cheat (cheat 900), or swing (swingthru 900).
