To perform Hanging High Pulls, hold the barbell with hands slightly wider than width of hips. Bend forward with your arms hanging straight down and your shoulders over the bar. In one quick burst, extend your legs and hips straight up, as if to jump. The barbell moves upward because of the momentum created by your legs. Allow your arms to "follow" the barbell with your elbows leading the way. Let the barbell glide back down, controlling it with your arms.
