Which is one of the four CrossFit Operational Models for defining fitness?

• A. Performance of Athletic Tasks (hopper)
• B. Hydration management
• C. Age-specific workouts
• D. Individual sport specialization

Answer: (A)

The idea being tested is how CrossFit defines fitness through different ways of looking at it, including a model that focuses on performing a wide variety of athletic tasks. In the hopper model, fitness is about the capacity to perform many different tasks, drawn from a “hopper,” under varying demands and time frames. This approach emphasizes work capacity across broad time and modal domains, not specialization in one skill or energy system.

That’s why the option describing Performance of Athletic Tasks (hopper) is the best choice. Hydration management matters for performance but isn’t a model for defining fitness. Age-specific workouts are a programming approach, and individual sport specialization focuses on narrowing a skill set rather than defining broad fitness.
