In class today we spent a lot of time working on a good contact of the bar on the thighs in the clean and at the hip crease in the snatch. This slow-motion video demonstrates extremely well what I am talking about. Notice how, once the bar has passed the knees, the thighs are explosively driven against the bar as the torso moves back. This achieves the most powerful jumping position to propel the bar upwards. As soon as the aggressive contact occurs, the movement is reversed, flexing the hips hard and pulling under the bar into a squat. This is what we want to achieve.
