Parallel bars skill
The "Diamidov" is a move on parallel bars. It consists of a swing down from handstand, through support, then releasing one hand and twisting the body a full turn, before regrasping in handstand. It is similar to the Stutz handstand, with the difference being that the Stutz involves a half turn only, but release of both hands.
