Mini Muscles: Meet Britain's Youngest Competitive Bodybuilder

While most teenagers are glued to their Playstations, 15-year-old Cosmo Taylor, from Inverness, Scotland, is more likely to be found honing his abs, quads and biceps in his local gym.

The mini muscles knows he can count on the support of his family, since his sister Bronwyn, 19, is a prize-winning powerlifter and father Andrew, 47, is a bodybuilder. 

And while the brother and sister duo continually push each other to improve their personal bests, Cosmo admits that there is some bubbling sibling rivalry between the pair.

Cosmo said: "I’m very competitive with Bronwyn. If she’s going to do 12 reps on something, I’ll do 15. It’s a sibling thing. 

"My dad and sister were a big inspiration, but sometimes my sister can be a big irritation."

And the rivalry has not escaped the attention of dad Andrew.  

He said: "Sometimes in the gym there can be a competitive edge to them, depending on who’s working what particular exercise that night, and if they both happen to be working the same exercise, they will feed off each other. 

"Bronwyn being that bit older, although she’s a girl and lighter than Cosmo, she will often just reel Cosmo in. She’ll let him go so far, but then she pulls it right back because she’s got a lot more experience than Cosmo. 

"Pound for pound she’s probably just as strong and in a lot of events she’s still actually stronger than Cosmo, something that Cosmo finds difficult to accept at times. But that’s just the way it is because Bronwyn does tend to catch everyone out with the way she looks.

"She’s very slim, slender, tall, elegant, but you put weights on the ground and she will outlift most people, even Cosmo, and that’s something he’s got to live with for a little while."

Bronwyn, who competes at national and international powerlifting events, works for the family’s removals business – and Cosmo is more than happy to lend a hand when he can.

She said: "Doing removals keeps me mobile but I wouldn’t class it as training, it’s a different type of strength but it allows me plenty of free hours to pursue my interests that I wouldn’t have with a nine to five job."

Cosmo, who started training informally at the age of 11, competed in his first show, the Silver City Classic Bodybuilding in Aberdeen, in November 2014, and has plans to enter more competitions in the future. 

But for now he is enjoying the attention that his super sized muscles bring him at school. 

He said: "Some people want to see my abs, see my arms, they think it's really cool. Some people even want me to be their personal trainer!

"I think it's quite funny, but they're always supportive, asking me if I've got any events coming up, there's a really good atmosphere."

And while some people have expressed concerns about Cosmo competing at such a young age, he is adamant that he is not putting himself at risk.

He said: "I’ve been training for almost four years now and I’ve been injury free. If you’re going to do something stupid, that’s how you’re going to injure yourself. It’s the same with any sport."
