In ancient Greece, men exercised nude in physical centers. The 19th century was influenced by German and Swedish gymnastics. The early 20th century introduced organized fitness inspired by military training. Post-World War II, bodybuilding became popular, and the 1980s was about aerobics and home workout videos. Today we are all about online workout and fitness wearables. This transition is visible in these vintage fitness ads which, by the way, prove that gay men existed long before it was cool to be gay! #Queer Up Gay Culture
