Since 1939, Joe Weider has been the primary force in advancing the sport of bodybuilding throughout the world. He has accomplished this through magazine publications, sponsorship of physical development contests—including the Mr. and Mrs. Olympia Contests—and the development, manufacture, and marketing of exercise equipment and nutritional products.

In 1939, seven years before he and his brother Ben founded the International Federation of Bodybuilders, Joe published his first issue of Your Physique magazine. In 1968, YP was renamed Muscle and Fitness, and today it is the flagship publication of the Weider Health and Fitness Company
publishing empire. Other Weider-published magazines are Shape, Men’s Fitness, Living Fit, Prime Health and Fitness, Fit Pregnancy, Cooks, Senior Golfer, and Flex.

A broad variety of Weider-manufactured nutritional aids and exercise equipment is distributed throughout the world.
