Joining Underground Gym is easy. You can sign up online, book a tour with our crew, or just drop by in person—your call.

We know everyone’s different, and your BMI only tells part of the story. To kick off your journey, we offer an optional Tanita Body Composition analysis during your first session to get the full picture of your fitness. Our goal? To tailor the workout to you, not the other way around.
‍
The Tanita scales measure:
‍Muscle Mass: Uncover the strength you’ve been hiding.
‍Body Fat Ratio: Focus on health, not just weight.
‍Hydration Levels: Keep dehydration in check so it doesn’t hold you back.
‍Visceral Fat: Get the lowdown on those love handles.If scales aren’t your thing, no worries. We’re here to help you see progress, and we’ll revisit the Tanita scales down the line to track how far you’ve come.

We hate to see you go, but if something’s not working, let’s chat. If you still need to cancel, just shoot an email to your club with a 30-day notice.

Mon-Fri: 5am-10pm
‍Sat: 6am-8pm
