Which of the following is a common barrier to being more active?


• having friends who like to be active
• not knowing who to ask about how to be more active
• having a regular doctor
• not having access to the Internet

The correct answer is "not knowing who to ask about how to be more active."

To arrive at this answer, we can examine the options given and determine which one represents a common barrier to being more active.

- The option "having friends who like to be active" does not represent a common barrier to being more active, as friends who are active can actually be a motivating factor.
- The option "having a regular doctor" does not necessarily act as a barrier to being more active, as doctors can offer advice on how to lead a healthy and active lifestyle.
- The option "not having access to the Internet" may restrict access to information and resources, but it doesn't directly hinder physical activity.

Thus, the only remaining option is "not knowing who to ask about how to be more active." This represents a common barrier, as individuals who lack guidance or information on increasing their physical activity may struggle to take the necessary steps to become more active.
