Members, punchcard, and day-pass holders get round-the-clock keyless entry via the Kisi app. The Fortress is always open for training, whether or not staff are on site. You never have to wait for staffed hours to get a session in.

Staff are on-site weekdays from 12:00 PM - 7:00 PM and weekends from 9:00 AM - 2:00 PM for tours, questions, and general assistance. Outside of staffed hours the Fortress operates completely self-service — detailed poster instructions at the door walk you through getting access if you are a first time visitor or need help.

Yes, and you don't need to wait around for staffed hours. Day passes and punchcards can be purchased ahead of time online or at the door. Once purchased, you get immediate 24/7 access — just show up, follow the access instructions at the entrance, and train. No appointment, no sales pitch, no nonsense - just train hard.

View passes & memberships

Yes — every visit, no exceptions. Checking in is how we verify that only authorized members and guests are in the facility, and it's a condition of your membership or pass. For open gym, scan your QR code from the Iron Fortress member app at our front-desk scanner. If the scanner isn't working or isn't there, check in manually for open gym on the front desk iPad. For class check-ins, use the iPad at the front desk.

Failure to check in will incur a $100 fee per occurrence (or such other amount as Iron Fortress may post from time to time), charged to the payment method on file. Repeated violations are grounds for termination of access without refund.

Tailgating is the same violation. Letting another person enter the facility on your credentials — or walking in behind another member without checking in yourself — is treated as a separate $100-per-occurrence violation, whether or not it was intentional.

Iron Fortress is a hybrid training facility — not a coaching-only gym and not just an open floor. We offer multiple avenues depending on how you train:

• Open Gym — 24/7 access to the full facility. Run your own program, on your own schedule. No classes required.
• Iron Fortress Athletics — Earn a spot on our streetlifting, powerlifting, or endurance teams and represent the Fortress at sanctioned events.
• Events — Competitions, meetups, and community happenings throughout the year.

Explore all training pathways

We support powerlifting, streetlifting, calisthenics, Hyrox, and endurance — plus general strength & conditioning. Every discipline has dedicated equipment and programming, and several have Iron Fortress Athletics teams with athletes who compete at the state and national level.

Learn about each discipline

Iron Fortress Athletics is the team layer of the brand. We field teams in streetlifting (USA Streetlifting), powerlifting (USA Powerlifting), and endurance. Members train together weekly and represent the Fortress at local, state, and national-level competitions.

The athlete program is currently under construction — we're building out the system for accepting new members onto the teams and aren't taking interest forms yet. The best path right now is to train your discipline at the Fortress.

Iron Fortress is built with competition-grade, specialty equipment across every discipline — calibrated plates, combo racks, multiple power racks, calisthenics rigs (including an indoor Kenguru Pro), specialty bars, cable crossovers, deadlift platforms, and recovery (dry sauna pods and an ice plunge pod). Every piece was hand-picked for serious training — no filler, no fluff.

Yes — our fridge is stocked 24/7 with everything you need before, during, and after your session: hydration (electrolytes, coconut water, etc), quick carbs (Gatorade, Powerade, juice, etc), protein (shakes and bars), and caffeine (energy drinks). Checkout is self-service on the front-desk iPad and runs on the honor system: you can charge the card on file or use a different card.

Before making your first purchase, set up your security PIN in the Iron Fortress member app under Settings → Account → Security PIN.

Abuse of the honor system — including taking items without paying — will incur a $100 fee per occurrence (or such other amount as Iron Fortress may post from time to time), charged to the payment method on file, in addition to the cost of the item taken. Repeated violations will result in fridge access being revoked and may result in termination of access to Iron Fortress.

Yes — the Iron Fortress Pro Shop is online. Rep the Fortress wherever you go.

Yes — Iron Fortress is a content-friendly gym. We believe filming your sets is one of the best ways to improve session to session: you can review bar paths, catch technique breakdowns, track progress over time, and learn from your own training the same way the best athletes do.

Content creation is encouraged so long as it's conducive to training and improving. The two ground rules:

• Don't film other members without their consent. Frame your shots so other people aren't the focus, and ask first if someone might end up in the background.
• Don't let the phone hijack the session. Equipment stays in rotation — don't monopolize a rack, platform, or station to shoot. Train first, content second.

Tag @ironfortressfit_ when you post — we love resharing what the community is working on.

Yes — Iron Fortress hosts and participates in competitions, meetups, and community events throughout the year. From in-house throwdowns to USA Streetlifting and USA Powerlifting meets, there's always something on the calendar.

Iron Fortress started as free weekly group workouts in Denver's parks — no paywalls, no excuses, just work. That grassroots community grew into a recognizable brand, then into a purpose-built gym. Today the Fortress is led by its three co-founders and a team of coaches and competitive athletes across multiple disciplines.
