They do everything together. They start out with cardio - he runs for a few minutes and she really works up a sweat on the stairmaster. They nuzzle when they're finished. Their outfits match just enough that The Watchers notice. While he lifts weights, she tries to look interested and important, failing. She's only interesteed in making sure everyone knows she is arm candy.
The other pair also do everything together. They lift weights at the same time, they do cardio at the same time. They wear tiny tanktops (akin to back-muscle thongs) at the same time. They need to go get a back wax at the same time. And a chest wax. And an arm wax.
Thank goodness the pairs weren't combined.
