"Double-unders require the athlete to propel the body upward and lift the feet up to several inches from the ground while making small, fast circular movements with the wrists in order to execute multiple turns of the rope with each jump. They develop dynamic balance, speed, quickness, agility, coordination, concentration, and cardiorespiratory efficiency." —Buddy Lee, "Jump Rope Basics, Part 2" (adapted)

There are many variations of the Olympic lifts. The qualifier "hang" describes the starting position of the bar. The hang snatch emphasizes the second and third pulls of the snatch, from the hang position with the bar at the hip to the full overhead squat receiving position and finally to the end of the lift with the bar overhead and the athlete standing. The timing, powerful hip extension, and coordination remain similar to the full snatch. However, the technical demands of arriving at the correct position are reduced compared to pulling the bar from the floor.
