Hang Power Clean, Hang Cleans, Power Cleans, Cleans, Clean and Press, Power Snatch and Snatch are under shoulders currently.
-I researched this mostly on bodybuilding.com. Although any of the pure Cleans not involving presses, I would almost think they would fall under Traps, maybe legs.
CriticalBench.com seems to want to put the 'Hang Cleans' under 'Legs'
If you find a definitive source for all these variations to the clean and snatch exercises, let me know and we can move them to different muscle groups.
