looking for a story from a year or 3 ago. Gym instructor, rival gym,

There was a multi part story, featuring a gym owner, helping at a rival gym, getting involved with an instructor at that rival gym and the relationship that developed. couples yoga may have been a topic but not sure.

Ive searched as may combinations of gym, instructor, yoga, etc and cant seem to find it.

Not sure if stories or series disapear, and that could be a possibility, but maybe someone remembers?

THanks
