Similar to a shoulder press.
Start - Hang clean the bar to the catch position.
Movement - Push the bar over your head with the help of your legs. Only use a slight bend in the legs to generate force from the ground up through the bar. The feet do not move. To get the bar in the finish position, some athletes are able to execute a double bend of the knees. The first is at the beginning, the second occurs just before lock out when the athlete's body drops out from under the bar into the 1/4 squat postion. Lower the bar to the shoulders while standing up and return it to the starting position.
