Gym Star Simulator i unlocked new factory gym in ! Update Guide, Pets, Ranks, and Tips

If you recently jumped back into Gym Star Simulator, the new Muscle Factory update gives you a fresh reason to grind. This gym-themed expansion adds a new area to unlock, along with new trainers, eggs, pets, belts, ranks, and season quests. If you want to keep moving efficiently, this guide breaks down what changed and what to check first in-game.

What’s new in the Muscle Factory update?

The update introduces a factory-themed gym area called the Muscle Factory. Based on the in-game event description and player coverage, the update also includes additional ranks and new pets.

New content	What players should know
Muscle Factory gym	A new gym area to progress into
New trainers	Bob the Worker and Steel Man are mentioned in player coverage
New eggs and pets	Fresh pet options appear in the shop/eggs
New belts	Worker belts were added
New ranks	New rank progression is available
Season quests	New seasonal tasks are part of the update
New code	Players referenced the code `overdrive`

If you’re returning after a break, it’s worth opening the game’s update or shop menus first so you can see what changed on your current account.

First things to check after logging in

When a big update lands, your best move is to review your rewards, boosts, and pets before spending cash or spins. In player coverage, the update included login rewards, spins, and a noticeable reset in how quickly the new content became useful.

Here’s a simple checklist:

Claim login rewards if available.
Check for any active spins or reward chests.
Review your best pets and trainers.
Look for the new code in the code menu.
See whether you can afford the new gym or egg options.

New code to try

Players in the update video referenced the code overdrive.

If you want to use it:

Open the game’s code redemption area.
Enter the code exactly as shown.
Redeem it and check your rewards immediately.

Codes can change or expire, so if overdrive does not work anymore, check the latest in-game code field or the game’s update notes.

New pets and eggs

The Muscle Factory update adds new pet options, including new eggs in the shop. Player coverage also mentioned limited pets that can cost Robux, but the exact lineup and usefulness may vary based on your current build.

What to do with new pets

Compare the new pets to your current best team.
Check whether any new pet improves your training or competition setup.
If you’re missing a key stat boost, prioritize pets that help with that specific area.
Save resources if the new egg odds are not worth the cost for your account.

Pet planning table

Goal	What to look for
Faster training	Pets that boost your current training stat
Better competition runs	Pets that improve competition-related gains
Rank progression	Pets that support the stat you need for ranking up
General progress	The strongest overall pet you own

Because updates can shift the meta, it’s smart to re-sort your pet inventory after each major patch.

Trainers, belts, and ranks

This update also adds new trainers and belts, which matters because trainer and gear bonuses can make a huge difference in progression.

Trainers mentioned by players

Bob the Worker
Steel Man

Belts mentioned in coverage

Worker belts

Rank progression

New ranks were added, and the video coverage showed that players may need to push multiple stats before they can continue ranking up smoothly.

Progression area	Why it matters
Trainers	Can increase training efficiency
Belts	Help improve your overall growth
Ranks	Unlock stronger progression and new goals
Season quests	Give you extra things to work toward during the update

If you are stuck, don’t assume the new gym is only about strength. Gym Star Simulator progression often depends on balancing multiple stats, pets, and equipment choices.

How to prepare for the new gym

If you want to reach the Muscle Factory faster, focus on your current strongest boosts first.

Good prep habits

Equip your best pets before starting a run.
Use your strongest trainers for the stat you’re training.
Don’t ignore belts or temporary boosts.
Spend resources only after comparing the new gear to what you already own.
Check whether you need more stamina, muscle, or another stat before pushing forward.

Practical progression table

If you’re missing…	Focus on…
Training power	Best pet and trainer setup
Rank requirements	Balanced stat grinding
Update rewards	Login and season quest menus
Cash for new content	Repeating the best available activities
Better efficiency	Equipment and boost optimization

Is the new gym worth unlocking?

For returning players, yes — especially if you like seeing fresh progression content. The Muscle Factory is the kind of update that gives long-term players a new climb and new reward targets.

It also looks like the update is designed to make old setups feel outdated, at least temporarily. That means players with strong old pets or belts should still revisit their loadouts before assuming they are already optimized.

Tips for smoother progression

Here are a few simple tips that can help after a major update like this one:

Check every reward menu after logging in.
Compare new pets against your current top pet, not just the newest one.
Use codes early so you don’t forget them.
Watch your requirements before walking into a new gym area.
Save Robux purchases for items that truly improve your build.
Revisit the shop and trainer list after updates, since new options may outclass older ones.

Final thoughts

The Muscle Factory update gives Gym Star Simulator a fresh layer of progression with new pets, ranks, trainers, belts, and seasonal goals. If you’ve been waiting for a reason to return, this is a solid one. Start by claiming rewards, checking the code, and comparing your best gear so you can decide how fast to push into the new content.
