Trick ID: 344
Make a full turn on the bar.
There are several ways to achieve this. The first is by changing your hand at the platform: During a swing, turn your hand on the bar as you arrive at the platform (try on the ground first!) then let go of one hand, make a full turn on the bar at the frontend and take the bar again. The second is changing your hand as you turn, similar to a Half Turn without a Force-out. The third is similar to the second, but with a force-out. See the videos to understand how.
Notes: First method, hand turned at platform
