3) feet positioning.
I'm not losing the bar because of forward position. The bar trajectory is actually back behind starting position. I'm not losing the bar because of the crash (which is minimal). The bar is lost because of 1) lack of tightness; 2) lack of arch; 3) feet positioning. 4) weak rack (minor); Excess flexibility might also be an issue, but it shouldn't be a problem given tightness. I can pause (hams to cavs) FS around 130 without an issue but 90 can cause problems in tightness. This is just an absurd problem that no one really has. If I could fix this problem cleaning 120ish wouldn't be much of an issue. The hips aren't supposed to move forward alot in any lift. They should be going more up than forward. Forward movement can displace the bar and is inefficient.
