FAQS

How do I sign up?

There are two ways to join:

1. Book a free tour. We'll show you around, help you pick the right membership, and you can sign up right at the front desk. Tap Free Tour at the top of the page to book.

2. Try a day pass first. If you join afterward, your $20 day pass goes toward your membership.

Do memberships require a commitment?

No. Month to month is available with no commitment. We also offer 3, 6, and 12 month plans, and the longer the commitment, the lower your monthly rate. If you can only train once or twice a week, ask about our Flex memberships.

Do you offer day passes?

Yes. Day passes are $20 and valid for one session (not 24 hours). Tap Day Pass at the top of the page to book an appointment. Memberships don't include guest privileges, but friends are welcome to come in on a day pass. They'll just need to sign our waiver.

What are your hours?

Members have 24/7 access and unlock the door with the GymMaster app on their phone. We occasionally close for events we host, like powerlifting meets, and announce those in advance. Tours and day passes are by appointment only. We don't take walk-ins.

I'm a beginner. Is this gym for me?

Yes. Our members range from people just getting into lifting to competitive powerlifters. Book a free tour and we'll walk you through the gym and help you get comfortable.
