Founded in 2005 and located under the Golden Gate Bridge, San Francisco CrossFit is one of the first CrossFit-affiliated gyms in the world. And when it comes to boxes, this one is literally a breath of fresh air, as it is a predominantly outdoor-based gym. The box boasts members such as Brian MacKensie of CrossfitEndurance.com and Olympic-lifting coach Diane Fu. The box also offers CrossFit for kids and teens, as well as programs for running, gymnastics, weightlifting, movement/mobility, and CrossFit endurance. (
