The Chicago CrossFit scene sprawls across the city, adding up to around 30 gyms—or “boxes,” as they’re often called by members. Windy City CrossFit claims to be the first CrossFit affiliate among Chicago gyms, and it remains hugely popular among members to this day. It’s not hard to see why; the converted warehouse space is filled with more kettlebells, rowing machines, and weight-lifting platforms than you can count. Alternatively, some CrossFit affiliates exist as extensions of other gyms in Chicago, Bucktown CrossFit being a section of Chicago Elite Fitness. Though some facilities rival larger Chicago athletic clubs by branching into services such as nutrition coaching and yoga, each CrossFit gym champions small group fitness classes as the foundation of its training.
