A Girl Found My Secret What Should I Do?

A girl in my class found my secret (my secret is i do martial arts since 4yo and im quite good at it and i have some 6 packs). That girl lets call her "x". She is very populer in my school. x become couple in like every single guy who worksout and have a "pretty" body. and all boys (not me by the way) has crush on her. Im a person who dont really like to show of so just my bffs know this secret. I never did a fight infront of someone. (If someone bullys me i just wait till school finishes). Im a bit shy and x is complete different. im super sure x will tell everyone about my secret. HELP ME! WHAT SHOULD I DO.
