Iron Fortress is a private gym built for people who take training seriously. Whether you're new to the barbell or chasing PRs, you belong here. This isn't a library; chalk is welcome, hype is encouraged, and so are you. No frills, no nonsense — just a community built to train hard.
Centrally located at 862 E 78th Ave in Denver, right off I-76 and I-25 — easily accessible from across the entire metro. We're just minutes from Thornton, Northglenn, Federal Heights, Westminster, Commerce City, Henderson, Brighton, Arvada, Broomfield, Lafayette, Aurora, and downtown Denver. No matter where you're coming from, Iron Fortress is worth the drive.
Not ready to commit? Try us out free of charge, grab a day pass — or a punchcard bundle — and come see what Iron Fortress is all about. No strings attached.
Try Iron Fortress free for 3 days. Three sessions to use across one week — perfect for seeing if we're the right fit before you commit.
Single-session access to open gym. Perfect for visitors, friends of members, or anyone who wants to experience Iron Fortress before committing.
Five visits at a discounted rate. Great for semi-regulars or anyone testing the waters before going all in.
Ten visits at the best per-session rate. Ideal for frequent drop-ins who want maximum flexibility.
