Position your feet so that your front foot is hanging off the side of the board at an 45 degree angle. Your foot should be in the middle of the board. Then you pop the tail and slide your foot up. When you are sliding up flick the side of the board with your front foot while leanin toward ur front foot, so it starts to flip. Keep your shoulders parellel with the board so you land back on it.
Tip: If you can only land it with one foot, put your front foot more on the edge so you can flick it faster and land with both feet. Try to land at least on the board upside down.
