Last Verified: July 2026 | 20 working codes | Checked this week
Gym Star Simulator is a bodybuilding game on Roblox where you train to get bigger. You lift at a station, your muscles grow, and stronger muscles unlock better gyms. Pets, trainers and boosts all speed that up, and they cost crystals and spins. That is what Gym Star Simulator codes are for. Here are all the ones that work right now.
There are 20 working Gym Star Simulator codes this month. They hand you Enchantment Crystals, wheel spins, boost items and even a free pet or two. One of them comes straight from the makers on the game’s own page, so that one is as safe as it gets. Codes are case-sensitive, so use the Copy button next to each one.

WORLDCUP is the newest one. The makers posted it themselves on the game page, so start with that. The code lists out there do not agree on how many spins Sweatmax gives. So we left that one general instead of promising a number.
Expired Gym Star Simulator Codes
These used to work but have run out. You can still try them, and they cost nothing but a few seconds, but most likely nothing will happen. We keep the rewards listed so you can see what you missed.

How To Redeem Codes in Gym Star Simulator
- Open Gym Star Simulator on Roblox and wait for the gym to load in.
- Press the Shop button on the left side of the screen.
- Click the Code tab inside the shop window.
- Type or paste a code into the box exactly as it appears here.
- Press Redeem to claim your crystals, spins and boosts.
Codes are case-sensitive and the capital letters are all over the place here. WORLDCUP is shouted, Sweatmax is not, and 50M has a number in it. Use the Copy button next to each code and you cannot get it wrong.
When Do New Gym Star Simulator Codes Drop?
New codes turn up when the game hits a big number of visits or when a themed update lands. You can see both patterns in the list. 100M, 200M and 500M are visit milestones, while HALLOGYM, BIGTURKEY and GOTHICSCHOOL came with events. The makers post the newest one right on the game page, which is where WORLDCUP came from. We check often, so bookmark this page and pop back when the game updates.
About Gym Star Simulator
Gym Star Simulator is a bodybuilding simulator made by the group Gym Simulator Club. You train each muscle at its own station and build up strength and stamina. That unlocks a run of themed gyms, and they get stranger the higher you climb. There are hundreds of pets to hatch, trainers to equip, and contests to enter. It came out in August 2024 and has passed 656 million visits.
Worth being straight about the shop. There are 50 gamepasses and about half are on sale. They sell the same things the codes give you. Hatch luck, aura luck, faster hatching, double muscle growth, extra pet slots, and trainers with big bonuses. So Robux really does speed this game up. Codes are the free version of that, which is why grabbing all 20 is worth the two minutes it takes.
