Weightlifting
Weightlifting was one of the sports at the anthic Olympics, so it's origins go way back. Modern weightlifting is a combination of (fast-) power and lots of training. The events consist of 2 lifts, the snatch and the clean & jerk. The snatch is performed in a continous movement with the arms held straight, the clean & jerk involves two separate efforts: the weight is lifted to the shoulders, the jerk follows with the bar thrust into a position overhead, bringing the feet together completes the lift. There are three tries in each. The International Weightlifting Federation was founded in 1920.
