Fit Beyond Expectation

Diablo CrossFit is one of the most recognized names in the CrossFit affiliate world. Founded in 2005, we have focused on our mission: “make our clients fit beyond expectation.” The result is an amazing gym with beautiful facilities, programs for beginners and experts, talented Coaches, a heritage of competition success, and most importantly, a fun, welcoming community of members.

We thrive on the amazing physical transformations of our every-day members who come to us to lose weight, get strong, train for an event, or simply improve their health, including first-time exercisers, weekend warriors, grandparents, stay-at-home parents, and students. And, we celebrate and learn from the incredible achievements of the many competitive athletes who also train with us.


Crossfit is a type of training that will make you stronger, fitter, tougher, more toned and build muscle across a wide range of different exercises. It uses varying degrees of intensity and timing in order to test your body in different ways. Crossfit is perfect for individuals who love a challenge, get bored by traditional routines, and enjoy learning new skills and want to look good, feel great and take pride in their health and fitness.

CrossFit uses functional full body exercises from weightlifting and gymnastics, along with running and other bodyweight movements. It is designed for universal scalability making it the perfect application for any committed individual regardless of fitness level, experience, age or ability.


Diablo offers more than 100 classes per week – far more than most other gyms. We also offer a variety of classes each day. Our locations are Open 7 days a week, including Sat 7AM – 1PM and Sun 8AM – 1PM in Pleasant Hill.


Our CrossFit classes always begin with a dynamic warm-up created by our experienced class coach. The warm-up is designed to gradually prepare you for the day’s workout. We included mobility exercises – targeted stretches – to help improve your range of motion prior to your workout. A CrossFit class at Diablo often includes strength or gymnastic training that is progressive each week. As your strength and fitness skills improve, you gain the ability to do more, aka, increased work capacity. Finally, our CrossFit classes always include a fun and challenging CrossFit workout (“metcon”) that will leave you feeling spent, and accomplished.


Diablo F!T is our high-intensity interval training (HIIT), bootcamp-style class. F!T is a cardo-style class with no barbells and no complex gymnastics. This class begins with a dynamic warm-up and mobility work and a longer conditioning workout that usually includes dumbbells or kettlebells, bodyweight exercises, rowing or stationary bike, and occasionally, some running. Your coach can substitute or scale any movement based upon ability, experience or physical limitations. This class is an impressive, calorie-burning, low-impact and high-heart rate, sweaty, fun experience.

Core & Accessory

Diablo C&A is an intense, 30-minute, core-strength training class that includes bodybuilding accessory work. C&A is a great complimentary class to Diablo’s F!T class. You’ll be doing planks, sit-ups, V-Ups, knee raises, bridge lifts, tricep extensions & bicep curls and a lot more. Diablo F!T class will help you tighten your core area and build strength in all the right places.

Fitness equals wellness. If you are injured, excessively sore or overly tired as a result of your exercise regime, then you are not “fit.”

The design of the Daily Workout is the MOST important difference between CrossFit boxes. CrossFit works, fast. But, more CrossFit does not equal better CrossFit. Excessive repetitive movements, improper scaling, or complex exercises under fatigue can leave people sore and possibly injured.

Diablo has been programming & tracking CrossFit workouts for clients since 2005. We have collected tens of thousands of results from members. Those results, along with ongoing client & Coach feedback has helped Diablo create incredibly effective workout programming for ALL of our clients, including our beginning members, our masters, our teens and top athletes.

Each month Diablo introduces new “progressions” for strength and gymnastic skills in addition to our CrossFit workouts. These progressions are programmed into our daily programming along with our CrossFit workouts for the month. By following progressions, our members improve – in strength and skill and CrossFit. Those improvements are reflected in the physical and fitness transformations of our members.

The quality of our workout programming is measured by the amazing results of our members. We encourage you to come in and talk to them – they enjoy sharing their success.

Diablo’s daily workout programming is now available for download to CrossFit affiliates and gyms around the world via SugarWOD. Please visit for more information.
