All the Gym Bros of the world owe a debt of gratitude to Lewis Dymek. A man named Lewis G. Dymeck invented the Dymek Curling bar (better known as the “EZ Curl” bar) and was granted the patent for it on May 23, 1950. As the story goes, Dymeck injured his wrist and training with a straight bar was too painful so he invented this unusual bar to work around it. The idea caught on… Soon many strength equipment companies began selling their own version of this piece of equipment and today you’ll find on ein pretty much every gym in the land.
