Google long-tail phrasing
Public search keeps surfacing Gym Star Simulator worlds, World 4, Deep Ocean Gym, and Muscle Factory phrasing as separate lookup intent instead of only broad beginner-guide traffic.
Gym Star Simulator Worlds and Gyms Guide
Use this page when you search Gym Star Simulator worlds, World 4, Deep Ocean Gym, or Muscle Factory. It turns scattered search, creator-video, and community-wiki wording into one support route with clear source boundaries.
Why this page exists
Worlds and gyms became their own long-tail cluster
This route exists because players keep searching for specific gym names and world numbers, while the current site already had a clean internal-link path from the wiki hub, rank guide, and Muscle Factory update page.
YouTube vocabulary
Creator videos still repeat Deep Ocean Gym, Pyramid Gym, and world unlock phrasing, which is enough public demand to justify a dedicated support route.
Community wiki surface
The public Fandom wiki still surfaced Worlds (Gyms), Anime Gym (World 10), and Muscle Factory (World 11) on July 14, 2026, which helps players navigate names even though it is not creator-owned.
Known public world references
Use names and source labels before you trust old unlock requirements
The page is intentionally collection-first: it helps players map search vocabulary to known public references without inventing a complete official world table.
Deep Ocean Gym
Sportskeeda's September 2, 2024 update article described Deep Ocean Gym as World 4 and tied it to the Planet Knight plus a cash gate. Use that as a known public reference, not a permanent verified requirement.
Zoo Gym
Sportskeeda's Update 3 coverage described Zoo Gym as the next world after Deep Ocean Gym. Treat it as a public path hint that still needs current in-game recheck.
Anime Gym (World 10)
The public Fandom wiki still surfaced Anime Gym (World 10) on July 14, 2026. It is useful vocabulary for player search intent, but not an official creator-owned route list.
Muscle Factory (World 11)
The public Fandom wiki labels Muscle Factory as World 11, while the official Roblox page and this site's update coverage both confirm Muscle Factory as a real gym/update concept.
How to use this route
Use the world name first, then move into the right support page
Most competing pages collapse world names into generic beginner text. This page gives the search phrase a home and then points readers toward the next exact action.
Use this page to identify the world or gym name players are actually searching for.
Open the rank progression guide before trusting any old world-unlock requirement or boss gate.
Use the Muscle Factory update page when the gym phrase overlaps with current update rewards, trainers, or exclusive pets.
Treat public Fandom pages and creator videos as navigation help, not as the final source of record for exact unlock numbers.
Next pages
Follow the internal path that matches your next question
A worlds page is only useful if it leads into the pages that can answer the next progression or update question.
Ranks
Check progression and unlock caution notes
Use the rank guide when a world name is really a question about unlock timing, boss gates, or your next progression checkpoint.
UpdateOpen the Muscle Factory watch page
Move here when the world/gym search overlaps with current update rewards, new trainers, exclusive pets, or season-quest wording.
QuestsOpen the season quests support page
Use this path when the world search turns into a question about weekly leaderboards, season quests, boost events, or free-pet quest rewards.
SourcesVerify official versus community sources
Use the source-status page when you need to separate creator-owned links from Fandom, older guides, or creator-video shorthand.
