Sports Illustrated's 2016 Fittest 50 List: Holly Holm, Jon Jones and five other UFC fighters named

Sports Illustrated -- not to be outdone with ESPN The Magazine's "Body Issue" news earlier this afternoon -- today announced its 2016 "Fittest 50" list, which ranks the world's fittest athletes in every sport, including mixed martial arts (MMA).

Leading the charge for Ultimate Fighting Championship (UFC) are former women's Bantamweight champion, Holly Holm, who landed in the No. 9 spot, and interim Light Heavyweight champion, Jon Jones -- who has packed on serious muscle since his reinstatement -- in the No. 4 position. Ronda Rousey (No. 19), Michelle "Karate Hottie" Waterson (No. 26) and Meisha Tate (No. 30) joined Holm in the Top 50, marking the second time this month that "Preacher's Daughter" has out-listed her competitive contemporaries.

Meanwhile, Flyweight champion Demetrious Johnson (No. 17) and, of course, Conor McGregor (No. 39) joined "Bones" on the male side of things.

To come up with the "Fittest 50," according to the release, Sports Illustrated editors, "worked with a panel of trainers, strength and conditioning coaches, performance experts, pro athlete coaches [to assess athletes] based on characteristics that define fitness and conditioning: strength, speed, endurance, agility, flexibility and skill in his or her respective sport."

In completely un-related news, Ennis-Hills' father bears a striking resemblance to Jon Jones:
