Official sources verify Muscle Legends as universe 1268927906, with training, gym unlocks, player fights, pets, moves, arenas, Strength badges at 2,500 through 1,000,000, Rebirth badges at 1 through 100, Brawl Win badges at 1 through 500, five named gym badges, four current Premium benefit statements, two group benefit statements, and four creator-listed strings. They do not publish formulas, requirements, complete rosters, combat rules, reward results, code expiry, odds, values, or tier rankings.
Exact identity and system inventory
Muscle Legends is universe 1268927906 and root place 3623096087, currently published by Muscle Legends Studio. The Roblox classification is Simulation and Incremental Simulator. The creator-owned description names training, new gyms, player combat, pets, moves, and arenas. This is the verified top-level inventory for the page. It does not prove a complete feature list or the rules beneath each system. Any wiki claim about trade, clans, quests, equipment, bosses, worlds, or currencies requires its own current source instead of being inferred from common simulator patterns.
Strength milestone ledger
Enabled official badges name 2,500 Strength, 10,000 Strength, 50,000 Strength, and 1,000,000 Strength. Their descriptions frame the sequence as increasing power, but do not state training rates, badge rewards, hidden prerequisites, or difficulty. The Rookie Lifter badge separately confirms a starting-training achievement. These labels can structure a versioned milestone card. Award counts are changing counters and should never be treated as the probability a new player will succeed. Claims about time-to-target need controlled current measurements that include boosts, Premium, pets, gyms, rebirth state, and update version.
Rebirth milestone ledger
Official badges verify 1, 5, 20, and 100 Rebirths. Descriptions say rebirth increases training potential or reflects greater potential, which supports the category-level relationship. They do not expose the first or later requirements, reset fields, multiplier, preserved pets, spin effects, caps, or best timing. A wiki may list the official milestone labels while holding a cost table and calculator. To verify a formula, capture the confirmation text, pre-rebirth values, post-rebirth values, one comparable training interval, and any active multiplier for multiple accounts or states.
Brawl milestone ledger
Roblox exposes Brawl Win badges at 1, 10, 150, and 500 wins. This proves that Brawls and a win progression exist, not how a Brawl is entered or won. The badge descriptions do not state arena rules, opponent count, match duration, scoring, combat moves, strength normalization, matchmaking, loss effect, reward, or whether private-server results count. A current Brawl guide needs an end-to-end capture from queue label through result and counter change. Until then, the wiki can safely preserve the milestones and explicitly hold all strategy and reward claims.
Named gyms and missing requirements
Enabled badges identify Frost Gym, Mythical Gym, Eternal Gym, Legends Gym, and Industrial Gym. Several descriptions say the gym was unlocked, while Industrial Gym currently has no public badge description. This is evidence for names and unlock-state achievements, not a complete ordered map. The public sources do not provide the entrance requirement, training stations, multiplier, portal, unlock reward, or whether the set changed in the latest update. Future gym tables should bind each row to a current live gate and training comparison rather than copying an old sequence.
Pets, moves, and arenas remain category-level
The creator says players collect pets, gain moves, and compete in arenas. No current official inventory used here names individual pets or moves, rarities, statistics, equip slots, evolutions, acquisitions, move costs, cooldowns, damage, arena modes, or rewards. Creator media supports visual identity but cannot prove these fields. A pet tier list or move ranking requires a complete roster, current comparable measurements, explicit criteria, and refresh policy. A simple wiki table would create false completeness, so the package keeps these claims in a verified-category versus unknown-detail ledger.
Creator-listed code strings and limitations
As checked on August 24, 2026, the official description lists megalift50, speedy50, spacegems50, and ultimate250. The exact spelling and creator publication are attributable. The checked source does not show where to redeem, what each string returns, whether it currently succeeds, whether a player can redeem it once, when it expires, or what failure message appears. Independent current videos demonstrate code demand but do not replace first-hand redemption. QuestSignal therefore records source status in the wiki and holds a public Codes route, rewards, active labels, copy buttons, and expiry history.
Premium and group benefit ledger
Creator text currently states four Premium benefits: double Strength from training, two extra Daily Fortune Spins, double chest rewards, and one additional pet slot. It separately advertises a group chest and one daily spin for joining the studio group. These statements are versioned creator claims. They do not define spin or chest contents, odds, cooldown boundaries, eligibility delays, stacking, geographic availability, purchase terms, or value. The wiki can quote no financial promise and should direct users to the current Roblox and in-game disclosure before spending or joining.
Updates and community sources
The demand check found 15 exact-name videos from 11 independent channels and 17,066 total views in its bounded window, including recent update and code coverage. This is an established interest signal and helps prioritize training, update, and code questions. It does not verify a mechanic merely because several videos repeat it. Community references can propose a reproduction task; official creator text, platform records, or trace-bound current captures decide whether the factual claim advances. Conflicts remain visible rather than being resolved by channel size or view count.
Held data and refresh policy
Exact training rates, rebirth requirements, gym gates, pet and move rosters, statistics, arena rules, combat formulas, currencies, shop prices, spin and chest odds, rewards, code results, expiry, values, and rankings remain held. Refresh after an official description, badge, media, or reproducible live workflow changes one of the supported systems. Counter movement and a new date are not enough. If a code string disappears from the official description, record the source-state change without guessing whether it expired or remains redeemable.
What this guide does not assume
This wiki verifies exact identity, creator-listed systems, current official milestone and gym badge labels, current Premium and group benefit wording, four creator-listed strings, and bounded demand. It does not certify formulas, requirements, rosters, statistics, arena rules, odds, financial value, code redemption results, expiry, rewards, rankings, or calculators.
Refresh trigger: Refresh when creator text, badges, media, or reproducible exact-game captures materially change a supported milestone, gym, benefit, pet, move, arena, code-source, or held-data state.
