The Whine Cellar
From Absit Omen Lexicon
The Whine Cellar is a wizarding gym owned by two muggleborn witches. It is located in Diagon Alley, and it is partially underground. There is a completely full weight room, several rooms for classes, magically altered cardio machines that were once electronic, a lounge area, a swimming pool and jacuzzis. There are also build-your-own obstacle course rooms for those who feel the spirit of parkour. It is open 24 hours a day, 7 days a week.
