Sophie Arvebrink first stepped into the gym as a hopeful teenage female bodybuilder just three years ago – a pretty but skinny Swedish 18-year-old weighing a very average 114lbs (52kg).
Sophie has now packed on almost 30lbs of solid muscle in just two years and now weighs in at almost 142lbs (64kg).
And, as is clear from her new arm training video, her arms are getting seriously big.
Sophie's love of bodybuilding has won her an international army of fans and transformed her physique.
She said: “I know how much I want huge biceps and I know I will build them. I know the physique I will be able to build in a few years, but I can not even imagine how much it will take out of me.
“I want to continue to add more muscle on me. And I'm really looking forward to strip the weight later, the muscles will stand out in all directions!”
