What term describes a lifestyle involving little physical activity?

The term that describes a lifestyle involving little physical activity is "sedentary." A sedentary lifestyle is characterized by prolonged periods of inactivity, often associated with sitting or lying down for extended periods, which can lead to various health issues. In contrast, an active lifestyle incorporates regular movement and exercise, promoting better physical and mental health. Addicted does not relate to physical activity levels and typically refers to compulsive behaviors or dependencies. Dynamic connotes movement and energy, which is the opposite of what a sedentary lifestyle embodies. Therefore, "sedentary" is the most accurate term to describe a lack of physical activity.
