Our Ann Arbor, Michigan location is the National Headquarters for all the O3 Sports. Since we opened in 2006 we have turned into one of the largest youth sports training company in the state!

Our instruction is designed to accommodate people of all ages and skill levels. Michigan's Team of dedicated coaches prides themselves on giving our youth, and adult athletes, the tools necessary to be successful on and off the court/field. We look forward to expanding our programs into other regions of Michigan in the near future.

During the year we offer CrossFit and Strength and Conditioning Class for Adults and teens, numerous youth camps, clinics, club teams, leagues, and after school programs throughout Ann Arbor, Saline, Dexter, Milan, Chelsea, Canton, and other areas.
