Which statement best defines CrossFit?

• A. Predictable, moderate intensity, isolated movements
• B. Fixed routines, high intensity, isolated skill
• C. Constantly varied, high intensity, functional movement
• D. Constantly varied, low intensity, aerobic activity

Answer: (C)

CrossFit is defined by three ideas working together: constantly varied, high intensity, functional movement. Constantly varied means workouts change frequently in type, modality, and stimulus so you train many different aspects of fitness rather than doing the same routine over and over. High intensity means work is performed at a challenging effort relative to your capacity, driving adaptation while remaining scalable to your current level. Functional movement refers to exercises that mimic real-life tasks and use multiple joints and muscle groups, like squats, presses, pulls, and carries, building work capacity for daily life and general sport.

The other descriptions miss one or more of these elements. Predictable, moderate intensity with isolated movements doesn’t reflect the varied, multi-joint, real-life task approach. Fixed routines with isolated skills contradict the goal of constant variation. Low-intensity aerobic activity fails to capture the high-intensity, full-body, functional nature that CrossFit emphasizes.
