The 1904 Experience

Smiling faces, big hugs, high fives and the heavy breathing after a good workout are just a few things you will find when you walk into CrossFit 1904. We were established with the mission to encourage, support, guide, and create the best experience of your fitness journey. Serving in Kearny Mesa, Tierrasanta, Clairemont Mesa, and the surrounding areas in beautiful San Diego, we are more than just your average CrossFit gym. We are looking forward to walking (and running) with you every step of the way to better health and wellness. Lifetime fitness.
