PC Controls — Keyboard & Mouse

Movement & Camera

+1 Muscle to Push Boulder on PC uses standard Roblox first- or third-person controls. 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.

Use W A S D to move, Space to jump, and Right Mouse Button held to rotate the camera. Toggle Shift Lock (period key by default in Roblox) when pushing the boulder so the camera stays aligned with your character during long interact holds.

Training & Interaction

E or Left Click on highlighted prompts activates gym equipment, egg machines, shop NPCs, and boulder push actions when eligible. Hold E on training stations that support continuous reps; tap for single interactions on menus.

Open the Roblox menu with Esc to adjust graphics if muscle ticks stutter. Lower shadows and disable unnecessary effects if you AFK train — see auto train scripts for automation cautions before using third-party tools.

Code redemption, when available, uses the in-game Codes button rather than a default key. Walkthrough: how to redeem codes.

• W A S D — Move character
• Space — Jump
• E / Left Click — Interact, train, push, hatch
• Shift Lock — Stabilize camera for pushing
• Esc — Roblox system menu

Menus & Inventory

Pets, rebirth, boosts, and settings live in on-screen GUI buttons unique to Doolittle!'s UI. Click the backpack or pet icon to equip hatched pets — multiplier changes apply immediately if the slot is free.

Rebirth confirmation is intentionally multi-step to prevent misclicks. Review timing breakpoints before accepting reset on keyboard.

Use our rebirth calculator on a second monitor to plan thresholds without alt-tabbing out of Roblox fullscreen.

PC Optimization Tips

Windowed mode makes wiki reference easier while grinding early muscle on the early game build route. Fullscreen reduces accidental focus loss during push segments.

If E stops working, click the game window to restore focus or rejoin the server. Roblox chat open in background sometimes steals keyboard input.

Input Mastery Across Sessions

Muscle sim progress is hours of repeated inputs. Small control improvements compound: stable camera during boulder pushes, reliable interact holds at high-tier gyms, and fast menu navigation for pet swaps. Platform guides under controls hub exist because push failures often look like stat problems but are actually released interact keys or mobile mis-taps.

Before blaming stats, confirm you are playing +1 Muscle to Push Boulder by Doolittle!, not a similarly named clone. Then review push alignment on the boulder route and muscle gates on unlock requirements. Controller players should read both console and mobile notes if using Roblox on handheld mode.

Wiki Methodology & Verification

This controls/pc 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.
