At 5'3" and weighing roughly 119 pounds, the 22-year-old television star is the smallest member of our list. That being said, she also has one of the most impressive grappling pedigrees. She's been training in mixed martial arts since she was a young teenager and has even competed in grappling competitions.

Sweeney discussed her martial arts background in a recent interview with Marie Claire. "I’m trained in mixed martial arts. I started when I was 14 and did my first competition at 18. It was a grappling competition against all guys a weight category above me, and I got first place. Those guys were probably saying, ‘Oh, we didn’t want to hurt her,’ but they were definitely trying."
