Which of the following is NOT a common barrier to physical activity?

Having personal trainers is not considered a common barrier to physical activity because personal trainers typically serve to motivate and guide individuals in their fitness journeys. They provide tailored exercise programs, accountability, and support that can enhance a person's motivation and provide access to the knowledge and skills necessary for effective workouts.

In contrast, lack of time, access to facilities, and lack of motivation are significant barriers that many people face when trying to engage in physical activity. Lack of time often stems from busy schedules, making it challenging for individuals to find opportunities for exercise. Access to facilities may be limited due to geographical location, availability of resources, or financial constraints. Finally, lack of motivation can arise from various factors, including personal circumstances, past experiences with exercise, or mental health issues, all of which can prevent individuals from starting or maintaining an active lifestyle.
