Jeff Tucker is the Coach for the CrossFit Gymnastics Cert. He and his team recently traveled to Sydney Australia with Andrew Cattermole of CrossFit Sydney.
This video from the CrossFit Again Faster crew is an introduction to the seminar. Tucker talks about how the seminar came about and what it was like taking it to Sydney.
He explains that the purpose is not to make gymnasts or gymnastics coaches out of the participants. Instead, they cover how to perform and coach fundamental strength, balance, and tumbling movements.
Gymnastics from a CrossFit perspective is competency in controlling your own body in three dimensional space. Like the Olympic lifts, they are worthy of a lifetime of study.
