If you’re looking for a modern gym with plenty of room for different workouts, Apex Gym is a great addition to your game. This fully furnished two-story fitness center has a sleek exterior with huge glass windows. The 30 x 20 lot comes with dedicated cardio and strength-training areas, which are filled with treadmills, weight machines, and other exercise equipment. There’s also an indoor swimming pool, so your Sims can take a break from the weights and get some laps in. Apex Gym uses no custom content. Make sure you activate bb.moveobjects before placing the lot.
Follow these steps to install Apex Gym on your Sims 4 game:
Download the mod file from the link above. Sims 4 mods typically come as .package or .ts4script files.
Open your Sims 4 Mods folder. The default location is: Documents/Electronic Arts/The Sims 4/Mods
Place the downloaded file directly into the Mods folder. You can organize mods into subfolders up to one level deep.
Launch The Sims 4 and go to Game Options > Other. Make sure "Enable Custom Content and Mods" is checked.
Restart the game if it was already running. The mod should now appear in your game.
Important: Always back up your save files before installing new mods. After Sims 4 updates, mods may need to be re-downloaded or updated by the creator.
Platform
The Sims 4 (PC/Mac)
Pro tip: If a mod stops working after a game update, check the creator's page for an updated version. Broken mods can cause the game to behave unexpectedly.
