Final answer:
Sedentary individuals should adjust their activity factor by incorporating more movement into daily life, with the goal of achieving at least 150 minutes per week of moderate-intensity aerobic activity and muscle-strengthening activities twice a week.
Step-by-step explanation:
The activity factor adjustment recommended for people who are considered sedentary involves incorporating more physical activity into their daily routine. The U.S. Department of Health and Human Services (HHS) advises that adults should, at the very least, move more and sit less throughout the day. While any amount of physical activity is beneficial, aiming for at least 150 minutes per week of moderate-intensity aerobic activity, 75 minutes per week of vigorous-intensity aerobic activity, or a combination of both is recommended for substantial health benefits.
Additionally, muscle-strengthening activities should be performed on two or more days per week. For sedentary individuals, adding low intensity or skill-based activities such as taking the stairs instead of the elevator, walking more, or doing household chores can act as a stepping stone towards these goals.
