Code Guardian

Personally finds and maintains every code on this page, with around-the-clock help from the rest of our Code Guardians.

Roblox Den's code tracker continually scans Roblox.com, social channels, user reports, game developer networks and other sources, and we've had 732,818 reports from players on Works, Doesn't work and new codes. But before any code is listed on our site, or marked as Expired, our Code Guardians check in-game that it works and that its rewards and requirements are right. That's why every code you try on Roblox Den works.

  1. Checks every code in-game

    Renato tests every new Muscle Training Simulator code in-game, and re-checks any code that enough players report as not working.

  2. Keeps this page up to date

    When Muscle Training Simulator changes how codes are claimed, adds a new requirement or launches a new promotion, Renato makes sure it's covered here first.

  3. Lists exact rewards and requirements

    Every code shows exactly what it gives and any level or gamepass it needs, so you know what you're getting before you redeem it.

Renato isn't the only Code Guardian around here: Erwin and Nicole check new codes for this game whenever Renato is away or asleep.

About Muscle Training Simulator

Muscle Training Simulator is a Roblox game where working out is your main objective. In this game, you are supposed to grow your muscles by performing various training routines where you lift heavy weights and grow bigger.

Don’t worry, all that strength won’t be for nothing. Once you start building some muscle size, you can participate in competitions where you drag heavy objects on the ground, such as pulling massive vehicles, for example.

With progress, you can also unlock new equipment for your workouts, as well as collect pets that give you amazing boosts. You can also obtain this by redeeming Muscle Training Simulator codes as well.
