CrossFit is a strength and conditioning brand which combines weightlifting, sprinting, gymnastics, powerlifting, kettlebell training, plyometrics, rowing, and medicine ball training. CrossFit contends that a healthy, fit person requires proficiency in each of ten general physical skills: cardiovascular/ respiratory endurance, stamina, strength, flexibility, power, speed, agility, balance, coordination, and accuracy.
It defines fitness as increased work capacity across all these domains and says its program achieves this by provoking neurologic and hormonal adaptations across all metabolic pathways. CrossFit athletes run, row, jump rope, climb rope and carry odd objects. They frequently move large loads quickly over short distances, and use powerlifting and Olympic weightlifting techniques. CrossFit athletes also use dumbbells, gymnastics rings, pull-up bars, kettlebells, and many bodyweight exercises.
