"Originally like most girls I wanted to be thin and toned so a lot of the things I did in the gym revolved around cardio and very light weights," she writes in her Anabolic Designs bio. "After going to the gym for a while I started to see a lot of changes within myself and realised that I had the ability to gain muscle and change my body."
But the British teen's choices were not without their detractors.
"I get a lot of compliments for my physique, but I get a lot of insults too," the 5' 7" McConnell, who recently turned 19, told The Daily Mail. "Quite a few people have said nasty things about me in the past."
Not that all men are mean to McConnell, though.
"I don’t have a boyfriend at the moment, but I don’t think my unusual hobby will put all boys off," she said. "Yes, some are a bit intimidated by my muscles, but others like them - I think it’s an acquired taste."
