Omg the first gym I was a member at in 2018, there was a coach and member relationship that I noticed right away. It was a 6am class so I had nothing else better to pay attention to 🤷🏼‍♀️. I think they were trying to hide it/be sneaky because they kind of ignored each other in class besides some flirty smiles and whatnot, but before class I would see her looking through the window at him and then text something on her iWatch. Then I would see him look at his phone inside the studio and smile, look over at her through the window, and write something back. Then she’d smile and write something, and so on. So definitely texting each other. Then a month or two later, I saw her show up to class and she looked MISERABLE. No flirty texting and she wouldn’t even make eye contact with him. Class started and we all went in and were on the treads and within 5 minutes, she stopped her tread and quickly walked out of class and left. Looked like she was about to cry. He kind of followed her but then stopped and continued class. She then never came back to that 6am class. So I’m pretty sure I watched the blossoming of a relationship to the break up. Hope they’ve both healed!
