Which of the following is NOT an aspect of physical fitness?

• A. Ergonomics
• B. Frequency
• C. Time
• D. Intensity

Answer: (A)

Physical fitness practice uses the FITT framework to plan workouts: how often you train (frequency), how long each session lasts (time), and how hard you train (intensity). Ergonomics, on the other hand, is about designing tasks, equipment, and workstations to fit the person and reduce injury—it's about safety and efficiency in the environment, not the structure of a workout itself. So ergonomics is not an aspect of physical fitness. For example, you might set a plan for three training sessions per week, 30 minutes each, at a moderate intensity, while ergonomics would address adjusting chair height or vehicle controls to protect your body during work.
