+1 Muscle to Arm Wrestle Wiki

+1 Muscle to Arm Wrestle is a fast-growing Roblox simulator from Beast Lifters where you train muscle, win arm-wrestling matches, hatch pets, rebirth for permanent multipliers, and push through multiple worlds filled with bosses and unlock gates. With a 97% rating and 27M+ visits, the game drops major content every Saturday — and this wiki is built to keep pace.

Whether you landed here searching for working codes, a rebirth timing chart, or the best pets to craft before your next world push, you are in the right place. Every page on this site is written for players who want actionable answers, not fluff. We track code verification dates, link related guides together, and explain systems like dumbbells, super rebirth, and egg hatching in plain language.

This is an unofficial fan resource. We are not affiliated with Roblox Corporation or Beast Lifters, but we play the game, test codes on live servers, and update pages after each weekly patch. Bookmark this hub and check back after Saturday updates for the latest rewards, balance changes, and strategy shifts.

Redeeming codes is the fastest way to jump-start a session. Beast Lifters releases new codes around updates, milestones, and holidays. Our codes page is verified regularly — last checked June 21, 2026 — and lists every reward before you spend time typing them in-game.

Currently active codes include rewards like free muscle, win boosts, galaxy eggs, and exclusive pets. Highlights from the latest verification:

• ILOVEKAZ — 300 Wins, 500 Muscle, 1 Turkey
• BUNNYHOP — 1 Bunny Pet
• GOLDENPAW — 1 Golden Cat Pet
• GALAXYEGGS — 10 Galaxy Eggs
• ROYALESALUTE — 10 Royal Eggs
• STRONGMAN — Freebies (Level 10+ required)

Codes are case-sensitive and can expire without notice after an update. If a code fails, read our codes not working troubleshooting guide or browse expired codes so you know what rotated out. For step-by-step redemption, see how to redeem codes or the dedicated code redemption guide.

New to +1 Muscle to Arm Wrestle? Follow this four-step loop before you worry about end-game crafting or super rebirth. It mirrors how experienced players progress through the first few worlds.

1. Redeem every active code. Open the in-game codes menu and claim free muscle, wins, boosts, and eggs listed on our codes hub. Even small boosts compound when you are low level.
2. Learn the controls and train efficiently. Muscle gain and win rate depend on knowing when to train, when to wrestle, and how boosts stack. Read the controls page first, then follow the beginner guide for your opening-hour priorities.
3. Hatch pets early and rebirth on schedule. Pets multiply gains; rebirth resets short-term progress for permanent multipliers. Do not rebirth randomly — use our rebirth timing guide and rebirth overview to hit breakpoints that unlock dumbbells and faster world clears.
4. Push worlds with a plan. Each world gates muscle, wins, or rebirth count. Check unlock requirements before grinding the wrong stat, and review boss strategies so you do not stall on a wall boss.

Once this loop feels natural, move to the fast progress guide and best build page to optimize your mid-game route.

Our guide library covers every stage of a +1 Muscle to Arm Wrestle run — from first rebirth to pet crafting min-maxing. These are the pages players open most often:

• Beginner Guide — First session checklist, early pet picks, and common mistakes that slow muscle growth.
• Fast Progress Guide — Route planning across worlds, boost usage, and when to stop training and start pushing wins.
• Rebirth Timing Guide — Exact breakpoints for standard rebirth and when super rebirth becomes worth the reset cost.
• Pet Optimization Guide — Which pets to keep, fuse, or replace; egg priority by world; crafting ROI explained.
• Code Redemption Guide — Where the codes button lives, mobile vs desktop redemption, and fix lists for typos and expired rewards.

Explore the full guides index for deep dives on items, quests, and update-specific strategies. Guides cross-link to tier lists and rebirth pages so you never have to guess which stat to push next.

Pets, eggs, and craft results define your multiplier ceiling. Our tier lists rank options by real in-game value — not hype — so you know what to hatch, keep, and fuse before investing rare materials.

Start with the tier list overview for the full ranking framework. From there, drill into specialized pages:

• Best Pets Tier List — S through C rankings with notes for early, mid, and late game.
• Eggs Guide — Which eggs to open at each world, galaxy vs royal vs basic egg value, and event egg windows.
• Pet Crafting Tier List — Fusion recipes worth chasing, bait crafts to avoid, and material efficiency tables.

Tier lists are updated after major patches when pet multipliers or egg pools shift. Pair them with the pet optimization guide and items catalog for boost and trail synergies that push a B-tier pet into A-tier performance.

Three systems carry most of your long-term power in +1 Muscle to Arm Wrestle: dumbbells, rebirth, and pets. Understanding how they interact prevents the most common mid-game plateau.

Dumbbells

Dumbbells are permanent stat investments bought with rebirth currency. They raise base muscle and win scaling before pets and boosts apply. Our dumbbells guide breaks down priority purchases by world and explains which dumbbell lines pay off fastest for arm-wrestle pushers versus trainers.

Rebirth & Super Rebirth

Standard rebirth resets run progress in exchange for a permanent multiplier. Timing matters — rebirth too early and you lose speed; too late and you waste hours on diminishing returns. Super rebirth is the deeper reset layer for players who have exhausted standard rebirth gains and need end-game scaling. Use the rebirth timing guide alongside dumbbell planning so each reset unlocks the next world gate cleanly.

Pets

Pets multiply training and win gains. Hatch from eggs, craft duplicates into stronger forms, and slot the best team for your current goal — muscle farming, boss bursting, or win streaking. The best pets tier list and crafting guide show which investments survive world transitions. For a full loadout snapshot, see the best build page.

+1 Muscle to Arm Wrestle spreads progression across multiple worlds, each with higher muscle requirements, tougher arm-wrestle opponents, unique bosses, and egg pools. Rushing the next world without meeting gates is the number-one cause of grind burnout.

The worlds hub maps every zone with muscle thresholds, win requirements, and rebirth gates at a glance. Supplement it with:

• Unlock Requirements — Exact numbers needed to enter each world and what to farm beforehand.
• Boss Guide — Boss patterns, recommended pet setups, and boost timing for wall bosses that block progression.

World pushes should align with rebirth milestones and dumbbell tiers. If you feel underpowered in a new zone, check whether you skipped a dumbbell tier, rebirthed off-schedule, or brought pets ranked too low on the tier list. Often a single rebirth cycle with targeted egg hatches clears the wall faster than raw muscle grinding.

Beast Lifters ships content on a Saturday update schedule. New worlds, pets, eggs, codes, balance tweaks, and limited events typically land on patch day — which means wiki pages, code lists, and tier rankings can change overnight.

Our updates page summarizes each week's patch notes in player-friendly language: what got buffed, what got nerfed, new codes to redeem immediately, and which guides we revised afterward. After every Saturday drop, we:

• Verify active codes on live servers and refresh the codes list
• Adjust tier placements when pet or egg pools change
• Update world and boss pages if gates or rewards shift
• Flag expired codes on the expired codes archive

If you only check the wiki once a week, make it Saturday evening or Sunday — that is when post-patch codes and strategy corrections are most reliable. Enable bookmarks for updates and codes so you never miss a free galaxy egg batch or limited pet reward.
