Bar on the blocks, explode from a dead start.
Stay patient and let the bar settle on the blocks, no bounce, every rep starts dead.
Starting the bar on blocks at knee height removes the first pull and the stretch reflex, so the quads have to generate everything from a dead stop, which builds serious rate of force development. The glutes drive the explosive hip extension and the shoulders take the wide catch overhead. Lifters use it to sharpen the second and third pull, fix a lazy finish, and get strong in exactly the position where snatches are usually won or lost.
Blocks isolate the explosive top half of the pull and remove momentum from the first pull. If your snatch breaks down above the knee, blocks let you rehearse that exact zone over and over.
No, let it settle completely. The whole point is starting each rep dead, so bouncing steals the stimulus you came for.
Close cousins, not twins. The hang makes you hold the bar in position, taxing your back and grip, while blocks take that away so you can focus purely on exploding from a static start.
