Standard Stable versus Novelty Movements

One of the methodologies of CrossFit is to select movements that are generally applicable to everyday movement. In other words, we want to get strong and competent in ways that are functional for our lives. Most people have to take out the garbage once a week, so we want to be able to lift heavy things. Most folks have to carry groceries, so we want to be able to carry heavy things.
A result of this is there is a standard stable of CrossFit movements. After about 6 months, you’ve probably seen them all.
Another methodology of CrossFit is to challenge students with new movements and games. Thus, we have novelty movements. The standard movements make you strong in a broad way. The novelty movements challenge us to see if that general physicality is paying off. It helps us answer the question: does this stuff work?
