John Garhammer, PhD, prepared this presentation to illustrate the modern pulling technique for the snatch and the clean. It is based on his high-speed film projects for USA Weightlifting since the early 1970s. These slides clearly illustrate the common use of the "power position" in order to optimize lifting performance.
For all the discussion these days about whether or not the so-called "double knee bend" technique occurs or whether one should plantar flex (rise on toes) at the end of the second pull, let these photos speak for themselves. Dr. Garhammer's work echoes the techniques taught in Harvey Newton's Explosive Lifting for Sports.
