In the photo, War Machine celebrated the male athletic build by showing off his chiseled abs and ripped biceps.
Just 11 hours after posting, the photo had notched over 1,000 "likes" on Instagram, and a handful of "favorites" on Twitter.
War Machine may not have done it on purpose, but the photo helped hype his Bellator 104 bout against Ron Keslar.
The nine-bout lineup for next month's Bellator 104 lineup is now official, and the evening features the semifinal bouts of Bellator's Season 9 welterweight tournament with Rick Hawn (16-2 MMA, 8-2 BMMA) vs. Brent Weedman (22-8-1 MMA, 8-3 BMMA) and Ron Keslar (10-3 MMA, 1-0 BMMA) vs. War Machine (14-4 MMA, 2-0 BMMA)
The Bellator 104 fight card takes place Oct. 18 at U.S. Cellular Center in Cedar Rapids, Iowa, and War Machine will definitely be one of the card's main draws.
War Machine, 31, is an American professional MMA fighter who competes in the welterweight division with Bellator MMA.
He is perhaps best known for his stint on the The Ultimate Fighter: Team Hughes vs. Team Serra as part of Team Serra, or for his relationship with critically-acclaimed actress Christy Mack.
He has been dating Mack for several months, and all is well with their relationship.
War Machine is featured in the Jan. 2014 issue of Hustler Magazine, along with Mack in a nude pictorial. Props to Mr. Machine for celebrating the male athletic form in a positive, classy manner.
Fight fans can see him back in the cage on Oct. 18 in Iowa.
