A Sensational Feat
A look at a vintage advertisement for the Milo Bar Bell Company, circa 1920. That's Anton Matysek lifting and supporting a bicycle with three riders, upping the ante on a feat originally pioneered by Thomas Inch.
As the ad states
"Walking with a weight of 560 lbs. in the manner shown above requires strength in every part of the body. That this man has strength is shown by his broad shoulders, deep chestand magnificently muscled arms and legs. He is a Milo Bar Bell pupil - a man who has obtained all his development through the practice of progressive bar bell exercises. Yet when he enrolled for our course of instruction he did not even have ordinary health and strength. He will give you a good idea of what you may expect to accomplish through the Milo Bar Bell system of exercise."
