A fitness model dubbed 'Miss Iron Bum' because of her rock hard posterior has treated fans to a rear-view video of her latest training session.

The 22-year-old - of Azerbaijani origin - said: "I was a very skinny child, had thin legs, and all my classmates made fun of me. So I decided to change the situation, I was tired of people looking at me. I started going to the gym, and had no idea how to build an exercise routine correctly so I just started working on the physical part, and one day I woke up and looked in the mirror and I saw some muscles.

Once I saw the result of developing muscles nothing could stop me."

Ever since she went online she has become a massive hit and earned the nickname the "Girl with the Iron Bum".

Local media described her as a fitness goddess with "an insane body, with curves bigger than the earth we stand on".

In addition to her stunning body, followers say she has a beautiful face and has been a hit in weight training contests.
