Was working a bodybuilding and expo show this past weekend and in the expo they have the Crossfit competition, like Baby said all the negative comments about that sport but let me tell you watching them it is intense, is it for me...no. It is a full body workout using Olympic style lifts, so with that being said you better make sure you work on the mechanics, technique, and form so you can lessen the chance of injury...but they say that is the sport that causes the most injuries when it comes to lifting.
