HOLLEY MANGOLD – 350 POUNDS

American female powerlifting champion Holley Mangold is reportedly one of the biggest—and heaviest—female powerlifters in history. Although Mangold stood at a mere 5 feet and 8 inches tall, she weighed a whopping 350 pounds. Interestingly enough, bigness probably runs in the family for Mangold, because her brother, NFL center Nick Mangold, is huge, too.

In 2013, she decided to make an investment in her health and join the reality television weight-loss competition, The Biggest Loser but was ejected for having lost only three pounds. The reason she gave for her abysmal performance on the show was that she was allergic to running on the treadmill.
