Activity level — which one fits you?

Pick the option that best matches a typical week. If you're between two, pick the lower one — most people overestimate how active they are.

Sedentary
Desk job or mostly seated day, little or no planned exercise.
Lightly active
Light exercise or sport 1–3 days per week (e.g. walking, light yoga, easy cycling), or a job with some movement.
Moderately active
Moderate exercise 3–5 days per week (e.g. brisk walking, jogging, recreational sport, gym sessions), or an active job.
Very active
Hard exercise 6–7 days per week (e.g. running, intense training, competitive sport), or a physically demanding job.
Extra active
Very hard daily training plus a physical job, or training twice a day (e.g. athletes in heavy training blocks, manual labour with extra workouts).
