Which statement is true about members working out under the age of 14?

The statement that members working out under the age of 14 need a parent or guardian present is accurate because it aligns with Planet Fitness's policies aimed at ensuring the safety and well-being of younger members. This requirement reflects the understanding that younger individuals may need guidance and supervision while exercising, as they may not have the same level of maturity, knowledge, or capacity to handle workout equipment safely on their own.

Having a parent or guardian present provides reassurance and support for the child and allows the adult to guide their workout experience, ensuring that the exercises performed are appropriate and safe. This policy emphasizes the gym's commitment to a fun and safe environment for all members, especially those who are still developing their understanding of fitness and physical activity.

In regard to the other choices, while it may seem convenient for younger individuals to work out alone or with only trainers, these options do not prioritize parental involvement, which is crucial in this context. Additionally, stating that younger members are not allowed to work out altogether would not accurately reflect the inclusive approach that Planet Fitness aims to uphold.
