About the show

Iron Culture was started by Eric Helms and Omar Isuf as a means of exploring the world of physical culture and attempting to distill a unified philosophy of lifting and to help listeners find greater meaning from the iron. It's now hosted by Eric Helms and Eric Trexler, who repeatedly beg Omar to return as a guest. Iron Culture focuses on dispensing practical, useful information to the listener, bouncing from history, to philosophy, to contemporary lifting culture issues, to science. The format includes casual conversations between the two hosts on a variety of topics, discussions with a panel of experts and interviews with authoritative figures in the lifting community. Iron Culture is proudly presented by the MASS Research Review.
