Denkova began her athletic career as a gymnast at the age of four, and switched to figure skating at about 8 or 9. She took up ice dancing when she was 12. Her first ice dance partner was Hristo Nikolov but they split up due to different ambitions. In 1996, Denkova had a successful tryout with Maxim Staviski in Moscow and he moved to Sofia to compete with her for Bulgaria. They soon became a couple off-ice, as well. In September 2000, Denkova / Staviski began dividing their time between Sofia and Odintsovo, near Moscow, Russia where they worked with coach Alexei Gorshkov and choreographer Sergei Petukhov.
