Mod: Fit Atmosphere (Gym) Moodlet Fix

This mod adjusts the multiplier for the Athletic Skill when having the Fit Atmosphere moodlet so that your sim will actually gain athletic skill when working out at the gym. Additionally, this mod also alters the Fitness Multiplier at the Gym, and will cause your sims to lose weight and gain fitness faster when working out at the gym.

The EA tuning for these two multipliers is broken, as they are both set to “.5” which actually means that sims will gain athletic skill and fitness at half the normal rate. This mod adjusts the multipliers so that your sim will benefit from being at the gym.

Important Details:

  • This mod does not require any Expansion or Stuff Packs.
  • This mod was built with patch 1.33 but it should be compatible for many other patch levels, as it appears that EA has never touched this particular XML in a patch. However, I cannot guarantee this as I do not have multiple patch levels available for checking.
  • Going by EA’s pattern, this mod is very unlikely to require an update after a patch, but check back anyhow just in case,


  • This is an XML tuning mod and should not conflict with any script or core mod.
  • This mod will conflict with any other mod that alters the BuffFitAtmosphere_0x7c229e6584751445 resource in the GameplayData.package .
  • This mod will conflict with corn!’s Fit Environment Multiplier mod available at ModTheSims.
  • This mod will not conflict with TwoftMama’s Lose Weight Gain Fitness Slower mod available at Naughty Sims’s Asylum, as that mod edits different XML files.
  • If you are not sure if a mod will conflict with another, use Delphy’s Sims 3 Dashboard Tool to check.

  3. I assume this still works with 1.42?

    • Yep, that is the purpose of the text in the right column. It’s really a pain to go through every single mod post for every single patch when I can just put a message on the right hand side when I’ve checked all my mods for compatibility. Thanks for using the mod and posting your question 😀

      • Well, I feel like a bit of an ass for missing that GIANT announcement the last time I came around. Thanks for taking the time to answer me even though I was being obtuse. 😉
