Which is a third CrossFit Operational Model?

• A. 10 Fitness Domains
• B. Performance of Athletic Tasks (hopper)
• C. Energy Systems/Metabolic Pathways
• D. Health Markers/Sickness, Wellness, Fitness Continuum

Answer: (A)

CrossFit uses several ways to frame how fitness is built and measured. The third model groups fitness into ten distinct domains, giving a comprehensive map of the attributes a well-rounded athlete should develop.

These ten domains cover a broad set of attributes—endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy. This framing ensures training addresses both capacity for daily life and performance across varied tasks, not just one area of fitness.

The sequence of models usually starts with health and wellness context and then considers how the body produces energy during work; once those foundations are understood, the ten-domain framework organizes training and assessment across all aspects of fitness. That’s why this model is identified as the third.

The other options reflect important ideas in CrossFit but belong to different aspects: a hopper-style performance test is a practical measurement of work across tasks, energy systems/metabolic pathways describe how energy is generated for work, and the health/wellness continuum frames fitness on a health-status spectrum.
