Is it appropriate for parents to take their children to the gym for fitness?

Not suitable. The equipment in the gym is too professional for children to practice. However, if there are courses, such as Latin, ballet, street dance and so on. Or have a swimming pool, you can take it with you.

Is it necessary to apply for a new card to bring children in? If the gym has a children's card, it means that there are courses and trainings specially designed for children; Don't go in unless you are allowed to.
