CrossFit studios pulse with high-intensity workout routines. As students undergo varied exercises from the scheduled Workout of the Day, a shoal of coaches circumnavigates the floor, guiding movements, ensuring safety, and stopping any public displays of affection between star-crossed kettlebells. Combining weightlifting, gymnastics, and track-and-field techniques, CrossFit aims to build the kind of resilience, strength, and versatility that lends itself to every athletic endeavor, equipping students with the stamina to conquer any challenge they might face. Instructors scale each workout up or down to accommodate individual levels of fitness or exercisers recovering from restrictive injuries.
