1. First learn frontside 180 ollies and be able to catch and land your kickflips without any problems.
2. Approach the hip, gap, bump (or anything else) in a kickflip position.
3. As you snap the tail into an ollie, turn those shoulders frontside and flip the board.
4. Stop the rotation, and catch the board with your feet.
5. Stick the landing clean, and roll away.
