What each one is actually built around
CrossFit combines weightlifting, gymnastics, and cardiovascular training, with workouts ("WODs") built around specific lifts, tracked loads, and skill movements like pull-ups, muscle-ups, and Olympic lifts. Bootcamp is circuit training, covered in full in the what-is-a-bootcamp-workout guide: bodyweight and light-equipment moves performed in timed rounds, with far less emphasis on any single lift or skill.
The four differences that actually matter
Which one actually fits which goal
If the goal is building raw strength, tracked numbers, and you're willing to learn barbell technique, CrossFit's structure gets you there faster because the loading is explicit and progressive. If the goal is general conditioning, fat loss, or you want a format with close to zero technical learning curve before you can train effectively, bootcamp's bodyweight-first structure removes the barrier CrossFit's lift technique creates for a first-timer.
The two aren't mutually exclusive. Someone who starts with the beginner bootcamp circuit to build a base level of conditioning, then moves toward loaded, tracked lifting once bodyweight training stops being challenging, is following a genuinely common and reasonable path, and it's exactly what the advanced progressions guide covers.
