Popa was born on 2 June 1997 in Constanța, Romania, and began gymnastics when she was four years old. She moved to Madrid with her family when she was six years old.[4] She competed at the Spanish Championships in 2008, and despite winning every event, she did not receive any medals as she did not yet have her Spanish citizenship. This was featured in a documentary by Informe Robinson. In mid-2008 she received Spanish citizenship.[5]
After she was finally cleared to compete for Spain, she sustained an elbow injury training on uneven bars, which required two surgeries and intensive rehab, leaving her out of competition for a few years.[1][6]
