Gym Classic is a spacious fitness center designed for Sims who want plenty of room to train, socialize, and build their Fitness Skill. The modern two-story build comes with multiple workout areas and a good selection of exercise equipment, including treadmills, weight machines, and other gym essentials. I especially love the warm wood flooring and bright interior since they make the gym feel inviting without taking away from the practical workout setup.

Follow these steps to install Gym Classic 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.

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.
