About This Archive
Expired codes are promo strings that once worked in +1 Muscle to Push Boulder by Doolittle! but have been disabled by the developer or hit their redemption limit. Keeping an archive helps players stop wasting attempts and understand what rewards looked like historically.
This wiki covers +1 Muscle to Push Boulder by Doolittle! (Place ID 136107936984073). It is not Sisyphus Muscle Push, Push A Rock, or +1 Muscle to Arm Wrestle — those are separate Roblox titles with different mechanics, developers, and code lists.
As of 2026-07-08, we have no confirmed expired codes for Place ID 136107936984073 because no official code has been verified live yet. When codes release and later retire, they will be listed here with the last known reward and expiration context.
Why Codes Expire
Developers expire codes to control economy inflation. A launch celebration code might grant a large muscle boost for forty-eight hours, then disable automatically when the event ends. Milestone codes tied to Like counts may never return once the goal is met.
Some codes expire silently — the UI still accepts input but returns "Invalid Code." That is why we move entries from the active codes page to this archive after failed verification passes.
Limited pet event codes documented on our pet events page are especially short-lived. Redeem those immediately using the redemption guide when active.

Avoid Fake "Expired" Lists
Scraped wiki pages often mix expired codes from unrelated simulators. Strings labeled "RELEASE" or "UPDATE" from other muscle games belong in those games' archives, not here.
If you find a code online claiming to be an old +1 Muscle to Push Boulder code, test it once on a public server. If it fails, check whether the source confused this title with Sisyphus Muscle Push or +1 Muscle to Arm Wrestle before reporting it to us.
For working codes when they exist, always use the live list on the codes hub. For redemption errors, see codes not working.
Community Code Discipline
Because +1 Muscle to Push Boulder is new, fake code pages spread quickly from other Roblox muscle games. Responsible players verify Place ID 136107936984073 before sharing strings in Discord or chat. When the first official code appears, redeem immediately on a public server using the redemption walkthrough, then archive retired strings on the expired list so newcomers stop wasting attempts.
Milestone codes often require collective Likes and Favorites on the Roblox game page — that is normal for incremental sims by developers like Doolittle!. Avoid "code generator" websites; they phish credentials. Pair legitimate boosts with the code redemption strategy guide so muscle or luck timers align with gym sessions or egg batches from the egg tier list.
Wiki Methodology & Verification
This codes/expired article was last verified on 2026-07-08 against live testing in +1 Muscle to Push Boulder on Place ID 136107936984073. We prioritize in-game confirmation over datamine leaks, copied code lists from unrelated muscle simulators, or unverified social reposts. When Doolittle! ships a balance patch, numbers in tier lists, unlock tables, and calculator defaults may shift until we re-test.
Cross-linking is intentional: muscle progression touches gyms, pets, eggs, rebirth, and boulder routes simultaneously. Use the guides hub, tier list hub, and tools hub together rather than reading a single page in isolation. If you notice outdated text after an update, compare the in-game UI first, then check the latest updates page for patch notes.
