3D Nollie.

1. Approach at a moderate speed, staying slightly over your back foot rather than loading the nose, with your eyes set on the slope where you want to land.

2. Unweight and bend your front knee deeply (toward 90 degrees) to flex the front half of the board and load it, just like the pre-pop crouch of a regular nollie 360.

3. Drive through the ball of your front foot to pop the board down and forward.

   At the same moment, tilt your shoulder line diagonally toward your direction of travel (drop the front shoulder, raise the back shoulder) and send your head to the inside of that tilted line. This tilt turns the plane of your spin from flat to angled, giving the off-axis (corked) rotation.

4. Right after the pop, pull your forearms in front of your chest and tuck both knees to make yourself small.

   Your spinning momentum is set at takeoff and can't be added in the air, so the tighter you tuck, the faster the same momentum carries you around.

5. Spot your landing early and let the rotation come around head, then shoulders, then hips, then board.

   Holding the tilted shoulder line all the way keeps the axis steady so you can read how far you've turned.

6. Once you see the landing coming, release the tuck and extend your legs, touch down back foot first, and bend both knees to absorb the impact.

You can pin your own clip to the tricks you've landed (My Video).
