+1 Muscle to Push Boulder Tier List Hub

How We Rank

Our tier lists for +1 Muscle to Push Boulder by Doolittle! rank options by long-term muscle efficiency, push power contribution, and cost-to-value at each progression stage. Rankings reflect community testing on Place ID 136107936984073 as of 2026-07-08 and will shift when patches rebalance pets or gyms.

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.

We use standard tiers: S (best in slot for most players), A (strong, worth investing), B (situational or mid-game bridge), C (early tutorial value only), and D (replace ASAP). Tier placement assumes you actively play — pure AFK setups may weight luck pets differently.

Tier List Categories

Incremental muscle sims split power across companions, random hatch outcomes, and static gym upgrades. Each category has a dedicated page with tables and reasoning:

• Best Pets tier list — Multiplier pets ranked for training and pushing.
• Best Eggs tier list — Which egg machines to pull at each muscle bracket.
• Gym Upgrades tier list — Training equipment priority order.

How to Use These Rankings

Early game players should follow the early game build before chasing S-tier hatch luck. Mid-game, cross-reference egg tiers with egg item details for exact costs.

Rebirth-focused accounts shift pet value toward multiplier stacking — see rebirth build and pet tiers together before sacrificing luck pets.

When pet events launch, limited units may temporarily exceed S-tier — watch pet events coverage for overrides.

Balance & Updates

Doolittle! can rebalance hatch rates or gym muscle per tick without notice. We update tiers after verified patch changes on the updates page, not rumor screenshots.

Use the muscle calculator to confirm you meet push gates before over-investing in cosmetic low-tier pets.

Disagree with a placement? Test alternate setups using the pet optimization guide methodology and compare push distance on boulder route checkpoints.

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.

Wiki Methodology & Verification

This tier-list 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.
