Energy balance

Sedentary behavior is defined as any waking behavior characterized by an energy expenditure ≤1.5 metabolic equivalents (METs) while in a sitting or reclining posture, and it is distinct from moderate-to-vigorous physical activity (MVPA).

Understand that sitting is not just 'not exercising.' It is a distinct behavior with its own health risks. Aim to reduce total sitting time, not just increase exercise.
