Ever wanted to go to the gym without, you know, the pain of actually going to the gym? Now you can, all thanks to Project Iron, which is an incremental Roblox game that lets you bodybuild without any of the work. After you put together your bodybuilder, you'll gain bulk by lifting and then compete to win various titles.

You'll likely want to reroll your stats quite a bit if you're hoping to be one of the best bodybuilders around. Out of Rerolls? You can get more with Project Iron codes, which can also net you some sweet temporary boosts. The game's dev team usually announces new codes in the official Project Iron Discord server, but we've gone ahead and done all the hard work for you by compiling this list of all of the working and expired Project Iron codes so you can get right back to building.
