If there was an award for wrestling’s greatest physique, Billy Gunn is in the conversation for winner.Decades on from his wrestling pomp as an Attitude Era icon, he looks as good as he ever did.Billy Gunn was about as ‘Attitude Era’ as they came in WWEWWEIn fact, at the age of 61, he’s still blowing the minds of nostalgic wrestling fans and fitness nuts all over the world thanks to regular workout videos that have proved a success across social media.Gunn is a regular fixture on the YouTube channel of Mike O’Hearn – a former Mr Universe and a strongman, powerlifting, and mixed martial arts specialist.WWE icon Billy Gunn still in insane shape at 61He’s proved a standout across the fitness fanatic’s channels, too, thanks to some crushing displays in the gym that have left viewers applauding and wincing in equal measure.Yet for Gunn, the path to essentially carving himself from granite wasn’t necessarily clear-cut. Making his WWE debut in 1993, he was a solid athlete but without a look and feel to set him apart.He first found success as one half of The Smoking Gunns alongside on-screen brother Bart Gunn, winning the WWE Tag Team Championships three times in the mid-1990s.A popular pairing, the Gunns were successful in their own right but it wasn’t until later in his career that Billy’s body began to dominate the wrestling landscape.After a brief stint in other pairings, he broke out in 1997 as one half of the New Age Outlaws with Road Dogg, combining brash mic-work with an increasingly imposing physique.By 1999, Gunn was crowned King of the Ring, and was often referred to as one of the best pure athletes in all of WWE. His singles runs included spells as Intercontinental Champion and Hardcore Champion, while his tag work cemented him as a cornerstone of WWE’s booming tag division in the late ’90s and early 2000s.Still performing and in frightening shape, Gunn has found a second home in the gym-focused content world, with his collaborations on O’Hearn’s channel proving so popular that one was this week declared the channel’s top collab of the year, helping it past one million subscribers.Gunn began his career as a relatively understated tag team wrestlerWWEGunn has performed on TV well into his sixtiesAEWGunn leaves no question unanswered in a workoutIG: titanohearnYouTube collab with Mike O’Hearn smashes recordsThe channel itself has amassed a staggering 534 million views in total, O’Hearn reflecting on Gunn’s participation, saying: “Nobody should be surprised. The world is weighed in on the biggest collaborations of the last year’s and Billy Gunn wins all collaborations.”For fans, the fact that Gunn still competes is incredible enough. At 61, he’s wrestled as recently as this month, and still appears on All Elite Wrestling TV. There, under his ‘Daddy A**’ persona, he’s part of The Acclaimed, having previously helped the group to a record 238-day reign as AEW World Trios Champions.What blows them away further still is his look and feel – one calling him an ‘age-defying beast’ on social media, another calling him a ‘legend of the game.’Another added of Gunn: “He’s always had a good body…. Guy looks 20 years younger than what he is.”A further fan applauded: “Fantastic shape, doesn’t look like he’s played a video game or watched a movie in his entire life.”Decades after wowing fans in the ring in WWE, Billy Gunn is still turning heads at the gym and on social mediaIG:titanohearn/WWE View this post on Instagram A post shared by TITAN CREW UNIFORM (@mikeohearnlifestyle)Another, replying to the O’Hearn content, added: “That’s a lot of beef there!!”, while a further fan quipped the duo should team up as a WWE tag team ‘Billy and Mike’ as a play on the Billy and Chuck tag team the wrestler was once a part of.The grappler’s in-ring days may be easing down – he’s unsurprisingly wrestled just 13 times in the last year – but his gym grind is anything but slowing.
