First off foot position. Start with your back foot on the tail like you are about to do an ollie. Then have your front foot just behind the bolts and have only the balls of your feet and toes on for your front foot.
Step2
Now is the movement. Start off by popping your board's nose up. (do this by pushing your back foot down) Next instead of going straight up the board like an ollie, flick your front foot right off to the top corner causing it to rotate and flip. Of course you'll need to move your feet out of the way i move my back foot up and front foot back.
Step3
Now for the landing while your board is spinning in the air watch for the griptape(top) to come up and when you start to see it put your feet down onto it try to land on the bolts so your board doesn't crack in half and bend your knees to reduce impact and roll away.
Tips & Warnings
Try to get a good clean ollie down before trying this and this will take lost of practice
