Going to the gym and watching other people sweat and grunt making deformed faces while I do the same is hard enough without having people's privates out and about! This gym in France and it's gym goers are totally cool with the idea though. If you're into the idea of lifting, squatting and running in the buff this is the spot for you!
The naked gym hours are weeknights between 9p and 11p and, as you can see from the tweet below, it's pretty busy out there! The spot is located in the 12th arrondissement, in the same building as the pool Roger Le Gall, which also opens to naturists at night and offers up a range of naked activities, including yoga.
Would you be willing to work out in the nude? I don't know how I feel about this naked working out thing....
