Five sport disciplines, each with programming and events; and 24/7 open gym when you want the floor to yourself. Pick a pathway — or combine several.
Programs by Sport
Calisthenics, streetlifting, powerlifting, Hyrox, and endurance — each with its own hub, equipment, and events.
Our full-size Kenguru Pro indoor calisthenics rig is one of the only installations in Colorado, purpose-built for muscle-ups, levers, planches, and freestyle. Bars at multiple thicknesses let you progress from beginner hangs to competition-level skills. Whether you're learning your first pull-up or training for a calisthenics competition, the Fortress has you covered.
Welcome to Colorado's first dedicated streetlifting gym. Iron Fortress features a full Kenguru Pro setup with weighted belts available for dips, pull-ups, and competition-style attempts. Train alongside the Iron Fortress Streetlifting team and some of the state's strongest weighted-calisthenics athletes.
Train on competition-grade equipment built for serious strength. Five REP PR-5000 power racks, Rogue Combo Racks, and four dedicated deadlift platforms give you everything you need to hit your next PR. The Iron Fortress Powerlifting team welcomes athletes at every level, from first meet to national stage.
HYROX blends running with functional work stations — the global race format and the training style behind it. Build capacity on rowers and SkiErgs, own sled pushes and loaded carries, and stack honest run volume so race-day pacing and transitions feel familiar, whether you are chasing your first finish or shaving time off the leaderboard.
Iron Fortress Endurance is our running and endurance discipline — programming guided by Division 1 athletic experience for runners and hybrid athletes who care about pacing, mileage, and getting faster. The free weekly Iron Fortress Run Club runs under this discipline as a separate community event, open to every pace and level.
Individual Access
For the self-directed athlete: full 24/7 access to every piece of equipment in the facility — squat racks, calisthenics rigs, cardio, recovery, all of it. You run your own program on your own schedule. No classes required.
