Beefcake magazines were magazines published in North America in the 1930s to 1960s that featured photographs of attractive, muscular young men in athletic poses. While their primary market was gay men, until the 1960s, they were typically presented as being magazines dedicated to encouraging fitness and health: the models were often shown demonstrating exercises.
Because of the conservative and homophobic social culture of the era, and because of censorship laws, gay pornography could not be sold openly. Gay men turned to beefcake magazines, which could be sold in newspaper stands, book stores and pharmacies.
In December 1945, gay pornography pioneer Bob Mizer founded Athletic Model Guild, or AMG. Mizer's AMG produced Physique Pictorial, the first all-nude and all-male magazine, and the film Beefcake documents his work and the growth of the Beefcake magazine industry. H. Lynn Womack published magazines such as Manorama, MANual, Fizeek, and Trim and was involved in the U.S. Supreme Court case MANual Enterprises v. Day (1962). From 1964 to 1967, Clark Polak published DRUM magazine.
In the 1960s, the pretense of being about exercise and fitness was dropped as controls on pornography were reduced. By the end of the decade gay pornography became legal, and the market for beefcake magazines collapsed.
Young Physique magazine was a prime example of this genre. It had a centerfold with a young model wearing a posing strap (g-string) with creative sets designed by the well-known gay photographer James Bidgood. Showing total nudity was illegal before 1962, so all models had to wear posing straps. Since Young Physique was widely available in drugstores and magazine stores all over the United States, even in smaller cities and small towns, buying a copy of the magazine is the way most young homophiles in the 1960s made their first contact with the gay world.
