What Is CrossFit?

CrossFit is a high-intensity functional fitness program that combines elements of weightlifting, gymnastics, and metabolic conditioning. Founded by Greg Glassman in 2000, CrossFit emphasizes constantly varied, functional movements performed at high intensity. Workouts — known as WODs (Workouts of the Day) — change daily and are designed to build broad, general fitness across ten recognized physical domains: cardiovascular endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy.

What to Expect

A typical CrossFit class lasts about an hour and follows a structured format: a warm-up, skill or strength work, the WOD (the main workout), and a cool-down. Classes are coach-led and performed in groups, which creates a strong community atmosphere. Expect movements like squats, deadlifts, pull-ups, box jumps, rowing, running, and Olympic lifts. All workouts are scalable — coaches will modify weights, reps, and movements to match your fitness level, whether you're a beginner or a seasoned athlete.

Who Is It For?

CrossFit is for anyone willing to put in the work, regardless of age or fitness level. The group class format and coaching make it especially appealing for people who thrive with structure and accountability. It's popular with former athletes, military personnel, first responders, and anyone who enjoys competitive, community-driven fitness. If you prefer working out alone with headphones, a CrossFit box may not be the right fit.

Typical Equipment

Barbells and bumper plates, pull-up rigs, kettlebells, rowing machines, assault bikes, plyo boxes, jump ropes, medicine balls, gymnastic rings, and wall balls.
