What can be classified as sedentary behavior?

Sedentary behavior is characterized by low energy expenditure, typically involving activities that require little physical movement and are performed while sitting or reclining. Sitting while watching a movie fits this definition perfectly, as it involves prolonged periods of inactivity that contribute to low energy output. This behavior is associated with various health risks, including obesity, cardiovascular disease, and other metabolic conditions due to the lack of movement.

In contrast, walking during lunch breaks, engaging in yoga sessions, and running a marathon all involve varying degrees of physical activity that elevate energy expenditure. These activities promote movement and can contribute positively to physical health, distinguishing them from sedentary behavior.
