Unlock Requirements — Gates & Thresholds
Last verified: 2026-07-08
Gate Types
+1 Muscle to Push Boulder uses multiple gate types: raw muscle stat, rebirth count, boulder checkpoint distance, and sometimes pet index completion.
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.
Exact numbers shift with patches — verify in-game UI and update this page after confirmed changes on updates.
Early Game Gates
Starter gym tiers: low muscle totals. First boulder push: first muscle gate on route. Second world: first major checkpoint clear.
Routing: early game build and beginner guide.
Mid & Late Gates
Advanced eggs and gyms tie to mid-route checkpoints on boulder route.
Rebirth count gates unlock multiplier shops — timing breakpoints.
Pet slot expansions documented on pets page.
Planning Unlocks
Use muscle calculator to estimate time to next gate.
Do not over-train past gate without pushing — opportunity cost rises.
World hub: worlds page.
Navigating World Gates
World design in +1 Muscle to Push Boulder ties visual biomes to muscle and rebirth requirements. The boulder route is the spine; side zones host egg vendors and gym tiers. Before farming a new world, confirm gates on unlock requirements and estimate time investment with the muscle calculator.
Backtracking to earlier worlds is usually inefficient except for limited index pets or event vendors documented on pet events. Push-first routing generally unlocks strictly better training than staying in starter zones.
Wiki Methodology & Verification
This worlds/unlock-requirements 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 If you notice outdated text after an update, compare the in-game UI first, then check the latest updates page for patch notes.

Fan wikis complement but never replace official channels. Like and Favorite the Roblox experience to receive update notifications when code milestones or new worlds arrive.

Extended Reference Notes
Reference pass 1 for "worlds › unlock-requirements" documents practical habits top +1 Muscle to Push Boulder players use after 2026-07-08. Keep a personal log of muscle per minute at your best gym, current rebirth multiplier, and latest push checkpoint cleared on the boulder route. When any of those three metrics stall for two sessions, switch guides: training stalls → fast progress and gym tiers; push stalls → push build and crush guide; hatch stalls → pet optimization and egg tiers.
Account security matters as much as strategy. Never run unverified loadstrings from the auto train page on mains you value. Never paste Roblox passwords into code sites promising +1 Muscle to Push Boulder rewards. Official promo codes, when they exist, are plain text in the Roblox description or Doolittle! socials — not executable scripts. This wiki covers +1 Muscle to Push Boulder by Doolittle!

Finally, treat this wiki as a living document tied to Place ID 136107936984073. Patch day checklist: read updates, re-test one gym tier and one egg tier, refresh codes, and skim tier list hub diffs. Thirty minutes of verification prevents hours of grinding with outdated assumptions copied from Sisyphus Muscle Push, Push A Rock, or +1 Muscle to Arm Wrestle.
