Introducing CrossFit 858

CrossFit 858 will provide fun, top notch, community based fitness training and will help you meet YOUR individual goals. (Not your “Globo gym” or “Big Box” trainer’s goals) Whether it’s to lose weight or put on muscle, when overall fitness comes first all else will follow.

All workouts can be performed “as prescribed” or scaled to your individual capacity. Whether you are an elite athlete or a couch potato trying to get back in shape, all levels of fitness are not only accepted but encouraged. You do not have to “be in shape first” to try CrossFit.

CrossFit 858 has two locations: Miramar and Mission Valley.  We have a combined 10,000+ square feet of functional space providing functional fitness to the San Diego community.

Come in today and see what you’ve been missing out on….

Our community is waiting for you.
