Do you know who had/has the biggest arms in the world? You are about to find out! These measurements and stats are for the biggest all-time arms in inches and not counting for “how” these arms came about. In other words, whether they were as a result of solid training or the use of steroids or other substances such as Synthol.
Lee Haney is not as well-known, but this guy won the Mr. Olympia 8 times. He was not only big but well defined as well.
