Angelova was a member of the CSKA sports club in Sofia.[3] She began gymnastics in kindergarten, and she was noticed by her first coach for her flexibility and ability to advance quickly.[4]
In September 2007, Angelova was ranked first in the junior all-around at the "Queen Margarita" international tournament in Varna.[5]
In March 2008, she won bronze medals with the ribbon and the hoop in the junior competition at the Grand Prix stage in Moscow.[6] That June, she came second to Russia's Yana Lukonina for her performance in the ball final at the Junior European Championships in Turin.[7]
In 2010, she was appointed to the Bulgarian senior women's team as a central member.[3] However, she never competed as a senior. She instead retired due to back injuries; a piece of bone broke off one of her vertebrae.[4] Iliana Raeva, the head of the Bulgarian Rhythmic Gymnastics Federation, blamed her coaches for not training her with her long-term health in mind, saying that she was over-trained and practicing too complex routines from a young age.[4][8][9]
In May 2013, a video of her 2008 Junior European ball performance went viral, garnering more than 7 million views. The wave of attention years after her routine and retirement upset Angelova.[4][10]
After halting her gymnastics career, she became interested in studying forensic medicine.[9]
