Here is my Sims 4 version of the Anistar Gym that's located in Anistsr City in Kalos. I chose the anime version because I think it's a lot more interesting than the game version.
This is a residential lot;it has 2 stories and a basement,and is located in Brindleton Bay.
Gym leader Olympia not included.
