Have you ever tried Olympic lifting with anything like a reasonable amount of weight?
Its really tricky, and requires massive explosive power, and excellent technique.....sounds like a sport to me.
Random fact of the day, did you know that many top olympic lifters have ridiculously high vertical jumps thanks to the nature of the explosive power they develop through training/competing as olympic lifters :)
