In this drill the gymnast begins with both hands in an eagle grip and jumps up to a handstand with eagle grip support afterwards to land flat down while maintaining a fully streched position and without loosing the grip on the bar. The drill can also be performed bouncing from a board, but either way, one of the goals is to show a vertically supported handstand without any pike before falling down.
The gymnast then makes a backwards roll to dislocate. The athlete must shift the wrists to maintain proper weight support at peak height or his body may collapse against the bar. Notice also the wrists shift on each inverted giants ascending phase to support.
