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.
Luck boosts from codes, pets, or boost items shift effective tier — hatch during luck windows when chasing S-tier pets from pet tier list.
Early Game Eggs (First Session)
S for stage — Cheapest basic egg: fast opens, feeds first muscle pet.
A — Second zone egg when muscle gate unlocks; stop here until push income rises.
Avoid premium eggs before reading early game build — currency starvation delays first boulder checkpoint.
Mid & Late Game Eggs
S — Highest unlocked standard egg with mythic chance aligned to your rebirth count.
A — Previous zone egg for bulk fodder and index completion.
B — Event eggs during pet events if limited pets beat standard mythic rates.
Late game players rebirth farming should consult rebirth build before dumping coins into cosmetic eggs.

Tier Methodology in Practice
Tier placement for +1 Muscle to Push Boulder combines muscle per minute benchmarks, push checkpoint clears, and hatch return on investment. A pet ranked A-tier might be S-tier during a luck event — watch pet events. Gym upgrades that look B-tier in isolation can become S-tier when paired with rebirth multipliers from the rebirth build.
Use tiers as decision support, not gospel. Record your own muscle per minute before and after equip changes using the muscle calculator. When Doolittle! rebalance hatch tables, revisit pets and eggs item pages alongside this tier list.
