Cute couple at gym

Was at gym about 2 hours ago. There was a guy and gal I assumed to be a couple, since the girl did not have clothing to signify she worked for the gym,

The girl is really fit like a Pilates instructor, the guy kind of has a DSS Bob but is pretty built and bulky. She was demonstrating certain exercises and correcting his posture when he was doing it. I thought that was really cute. Whether she’s an instructor in private clothes, they’re just friends, couple whatever, just love seeing a teacher teach a student like that.
