Flexing his pecs and admiring his stage tan, Cosmo Taylor starts his posing practice. He lately competed in his very first bodybuilding show against a line-up of muscular physiques from all over the United Kingdom.
But unlike his fellow contestants, Cosmo leaves the house every morning with his school lunch-box and a kiss on the cheek from his mother - because he's only 14 years old!
He started training at just 11 years old and lifts weights for an hour every day.
He also does cardio before going to school to keep his body fat below eight percent.
And as the youngest member of a super-fit family of four, he enjoys firm support from his biggest fans - his mother and father.
You gotta see it to believe it!
