Just no belly stain: How Knoll and Lotfi jump from the tens

Anton Knoll and Dariush Lotfi stand with their backs to the jump. Only their tips of the toe touch the ten -meter tower. They raise their arms over their heads, stretch through. The next moment they get momentum, go to their knees and jump back about half a meter. Synchronous lifts the two from the platform and crouched together.
