The fs 180 ollie is a fun and easy trick, ideal if you just learned your ollie and want to take it to the next step.
1. Start in the ollie position, with your back foot a little more to the heel side.
2. Crouch down to jump and wind your arms in the opposite direction.
3. Push your back foot down fast to pop the board. Because you push on the heelside of the tail, the board will rotate 180 degrees frontside.
Swing your arms to help with the rotation.
4. Try to land a full 180 degrees and roll away.
