What is CrossFit?

CrossFit is many things

For Chino CrossFit, it is three things: a community, a definition of measurable fitness, and a prescription for attaining that fitness.

The community that forms around doing CrossFit workouts is central to CrossFit’s effectiveness. The shared experience of intensity and physical improvement, of overcoming mental and emotional hurdles, of knowing each other’s pain and cheering each other on…this shared experience forms an inclusive community. That’s why we tend to show up early and stay late.

Coach Greg Glassman “was the first person in history to define fitness in a meaningful way” (CrossFit Games website). That definition is this: increased work capacity across broad time and modal domains.

What does this mean? It means having greater strength (work capacity), better endurance (time domains), and more mental and physical flexibility (modal domains). With this kind of definition, we can easily measure fitness with nothing more complex than a stopwatch, a scale, and a tape measure. We’re essentially talking physics: How quickly can you move a particular load over a certain distance? How many times can you perform a certain set of movements (with a load or just body weight) in a limited amount of time?

So, in CrossFit, fitness isn’t necessarily about getting that “beach body” or those six-pack abs. It is about being ready for athletics, adventure, and life in general. However, if you’ve seen the changes in body composition that our dedicated members have experienced, you’ll know that being fit and looking sexy tend to go together.

CrossFit’s prescription for achieving this fitness is a regimen that focuses on “a broad, general, and inclusive fitness – not only for the unknown, but for the unknowable” (CrossFit Games website).

We believe in the philosophy that by training for a wide variety of sports and activities, we become more generally fit. It has been said that life punishes the specialist. CrossFit’s specialty is not specializing. Regarding the actual workouts, a phrase you’ll often hear is “constantly varied, high-intensity, functional movement”.


By “constantly varied”, we mean that each day is a different workout, and may include any combination of gymnastic movements, olympic weight lifting, metabolic conditioning, or an assortment of other types of movements…some of which might involve a partner or even an entire team.. Because the workouts are always different, you are likely to be faced with at least one thing you are not good at. Facing these challenges alongside your classmates often becomes fun. It’s not necessarily the kind of fun we normally think about, but it’s a kind of fun you can get hooked on. It’s the kind of fun that elicits tired but earnest high-fives after a workout.


Intensity during workouts is key to getting real results. All CrossFit workouts can be modified for any level of fitness, but what remains unchanged is the level of intensity. With proper modifications and weight scaling, the experienced athlete and the novice should experience the same level of intensity. This is one of the reasons that such a camaraderie can form around these workouts. We’re all working equally hard regardless of the fitness we walked in with.


“Functional movement” is everyday movements such as running, jumping, pulling, and climbing that actually prepare you for life outside the gym. The movements in CrossFit workouts help you perform better athletically, but they also make you better at doing things like getting that 40lb. bag of dog food into the trunk or helping your buddy move out of their upstairs apartment. That’s perhaps one of the cons of doing CrossFit. People will always be asking you to pick up heavy things. The pro is that you get to pick up heavy things!
