so once you get to around mid thigh (depends and arm length and grip width) you’re more so pulling the bar in to the hip crease. it shouldn’t be an bang but more of a brush to keep the bar moving vertically and not push it out. from there the arms are pulling up and under
it’s not how hard you can pull it off the floor. only lifts are about speed through the middle (second pull).
1st pull is floor to mid thigh. you want to maintain the same back angle to keep your hips/hammies loaded for the second pull
2nd pull you’re pulling the bar in the hip minimizing distance from the thigh. knees move forward slightly as you move into full extension
3rd pull is pulling/guiding the bar into the high pull position (elbows up and out) and finally actively pulling yourself under the bar.
it’s all positions and timing
