Kickback
The Kickback is a really old freestyle trick. Its a half flip backwards and then a full flip back forwards. Its done by placing your front foot on the front bolts and your back foot only with your toes in the middle of your board. You start pushing down on your toes and when the board catches your toes, you jump, give the board a flick and after the board flips you catch it and land back on the griptape.
