and all, she's cute
With that said, it's not a big deal; there's a woman I follow on Facebook and IG who makes comedic edited reels of people doing weird crazy stuff at her gym.
White man need to relax; she ain't hurting anybody, and the guy she was recording on the reel probably doesn't even know such a video exists.
The gym is a public recreation, which means anybody can film you with or without probable cause or permission, so no laws are being broken as long as the video being obtained isn't used for malicious reasons. We're all being filmed to some degree without our permission, whether it's somebody's smartphone or passing by a security camera.
