As many times as I say it while I'm coaching the various Olympic Lifts I'm not really sure if people are comprehending the point I'm trying to make. This video gives you graphic proof regarding this point. Watch it a couple times so that you can the various transitions and execution elements you MUST hit to be successful at this lift. Remember - anyone can move a sub-maximal weight around using a secondary or tertiary power source (arms, shoulders, etc.) but you have to have your technique really dialed-in to start moving bodyweight or more towards the overhead position.
