yes, exactly what marcus said! learn the feel from the hang without worrying about the timing of the double knee bend, then go down to the floor and use all the momentum for the big full lift. . 3 position, 4 position, all good, but get good at tghe hang first. another tip i find that i need to tell beginners is that when they pick it uop to the hang for the set, do it exactly like the lift as far as the startign position etc. soem just tend to stand up with it from different posdition, and miss the chancce to practice that for wehn they put it all together.
i like the term "tall cleans" - what we call cleans from full extension. teaches the feel of throwing your body DOWN into the full sqaut at that point, NOT continuing to try to pull it higher like the common power version. -g
