They can always control their diet, watch the carbs they eat and do pushups and other exercises with or without dumbbells. They can even go upstairs, take the elevator to the lobby and do it again.
Actually not only escorts are thinking (and joking) about bodies before and after the quarantine...
If you have friends and family on WhatsApp, FB, I'm sure you have received videos and photos making fun of folks getting out of shape because of not being able to hit the gym.
One more thing, most escorts know young in shape men might occasionally call them but they're not the usual clientele. They'll deal with clients who put on a few pounds because of staying home.
Yes but maintenance also depends of daily good habits when it comes to food not only exercises. Some guys (clients and escorts) now on a more sedentary lifestyle might feel tempted to "treat" themselves.
