Your PIN will only give you access to gyms that are included in your membership. If you have an off-peak membership, you will only be able to enter the gym during your gym's off-peak hours. You can view those, or upgrade to gain access at all times, on your Member's Area!
If you're unsure how to enter, check out this handy article.
If you still can't enter, please press the assistance button in the entrance and one of our team will come to help. They are around from 9am - 5pm.
