Inside the no-fluff, no-frills gym, patrons sweat their way through comprehensive group workouts. Adapted from sports including weightlifting, gymnastics, and track, CrossFit's mélange keeps the body constantly working toward change, against which muscles rebel by bulking up or turning into washboards. During each 35-minute class, both men and women build more than just muscle, as multifaceted sessions also focus on endurance, speed, balance, agility, and flexibility.

For a quick leg up on getting fit, the gym's boot-camp classes immerse students in intense, varied workouts designed to burn fat and whittle away inches quickly. Six days a week, instructors might challenge students to rope climbs, sit-ups, sprints, or kettlebell exercises, always incorporating both cardio and strength training to achieve results as quickly as possible. For those new to the gym's programs, boot camps are an ideal way to gain the strength and endurance necessary to succeed in the more intense CrossFit classes.
