I like doing Cleans....but once I get over 245lb, I realize just how crappy my form really is....I need coaching to fix the multitude of form issues, and honestly I don't have the time. Cleans work great for my power, but I need to sacrifice the time form my core lifts to do them justice...
People don't do them, because they don't want to hurt themselves, and they are very aware how easy it is to get hurt when you are throwing weight around.
