This includes activities such as walking, running, weightlifting, and playing sports. Choice B is incorrect because an elevated heart rate may occur from other factors such as stress or anxiety, not necessarily from physical activity. Choice C refers specifically to a type of physical activity that involves sustained, rhythmic movements of large muscle groups, while choice D refers to a specific type of physical activity focused on increasing muscle strength and mass.
