Pictured is a 15-year-old boy named Billie Barton training in the hopes of appearing in a film. He’s using what is called a chest expander. With this device, you can either add springs or take them off to increase or decrease resistance. This was a popular exercise at one point because they were mobile, easy to use, and somewhat effective. However, today the only chance of seeing one is most likely in your dad’s garage from when he used to work out at home in the 1980s. They are a little dangerous, with the springs potentially breaking easily, and you won’t see them at a gym anymore.
