John McWilliams was an incredibly strong and powerful bodybuilder of the late 1940’s and 1950’s who was well known for his arm development. While many bodybuilder inflated their numbers, John McWilliams used to offer a reward if anyone could measure his arms at LESS than 19-1/2 inches! He ran a successful gym in Dayton, Ohio (The Dayton Health Studios at 131 E. Third Street) and wrote several training articles for Iron Man Magazine. He also had his own arm development course, “Big Arms for You” which can currently be found in its entirety posted in The Iron League.
