Rebirth Timing — When to Reset

Why Timing Matters

Rebirthing too early wastes hours recovering; too late stalls multiplier growth in +1 Muscle to Push Boulder. 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.

Deep dive: rebirth page and timing breakpoints.

Signals to Rebirth

Muscle gain per minute flattened over two sessions without affordable gym upgrades.

Rebirth menu shows next multiplier ≥15–25% faster recovery vs staying (test with calculator).

Push progress blocked and extra muscle would not clear gate within similar time as rebirth recovery.

Signals to Wait

One more gym tier unlocks within short push attempt — see boulder route.

Active luck event for hatching S-tier pet before reset — pet events.

First rebirth ever: ensure you understand what resets — read rebirth build.

After Rebirth

Rush gyms, re-equip pets, push early with multipliers. Chain second rebirth only after breakpoint math confirms — not vanity.

Guide synergy: fast progress and pet optimization.

Progression Sequencing

New players should chain guides in this order: beginner, fast progress, pet optimization, rebirth timing, then situational pages like code redemption and avoid boulder crush. Skipping ahead to rebirth math without push fundamentals wastes resets.
