Before you join
Good to know
Can I train at both gyms?
Yes! Your Madhouse membership gives you access to both Rotherham and Carlton, as well as any future Madhouse Gym locations. One membership, every Madhouse gym.
Are the gyms open 24 hours?
Madhouse currently advertises 24-hour access for active members. Staffed hours are separate, so your first visit or access setup may need to happen while the team is there.
Do I need to be an experienced lifter?
No. Both gyms welcome beginners and experienced lifters. You can take time to learn the gym and train at your own level.
