Four new codes just landed in Muscle Military, the Roblox auto-clicker that blends gym grind with military-style progression. All four were added on June 16, and none of the older codes have expired yet, meaning this is the cleanest code window the game has had since launch.
What the new codes actually give you
Here's the lowdown on every active code right now:
The standout here is 99Endurance. A flat 250 Luck bump combined with doubled stamina recovery for 15 minutes is the kind of stacking bonus that compounds fast when you're grinding officer promotions. burpees99 is worth grabbing too since the autoworkout potion handles clicking entirely while it's active.
How to redeem codes in Muscle Military
The redemption flow is straightforward once you know where the code box actually lives:
- Launch Muscle Military on Roblox
- Click Menu in the top left corner
- Select the Band-Aid icon
- Paste your code into the Enter code box
- Hit Confirm to collect the reward
New codes sometimes only register on fresh servers. If a code returns an error right after release, wait for a server reset and try again before writing it off as expired.
Why the Luck stat matters more than it looks
Stamina boosts get the attention, but Luck is quietly the more valuable currency in Muscle Military. Higher Luck influences drop rates during training sessions, which means better gear and faster officer rank progression over time. Stacking the 250 from 99Endurance on top of an active autoworkout potion is the closest thing the game has to a turbo mode.
The 2CPS auto-click from MAJORMUSCLES is more situational, but useful if you're in a session where you want to push through a specific officer tier without babysitting the screen.
For players who enjoy this style of Roblox progression game, the free spins and currency codes in the Parkour Champions codes guide for June 2026 follow a similar redemption format and are worth bookmarking alongside this one. If you prefer combat-focused Roblox games, the VV Ultimatum codes for June 2026 cover free Clan Rerolls and Focus Elixirs that are currently active.
No expired codes yet, but that window closes fast
As of June 16, every code listed above is still working. That's a rare situation for Roblox games at this scale, where codes typically start expiring within days of a major drop. The fact that the game has zero expired codes right now means you can redeem all four without checking individual validity.
That said, stamina and Luck codes tied to specific durations tend to get pulled once the developer pushes the next content update. Redeem these now rather than saving them.
