Trainers
Every trainer the community wiki documents, with its bonus and how to unlock it.
Trainers give a percentage bonus to muscle growth, stamina growth, competition winnings or egg luck, and unlike pets their bonus is a flat percentage rather than a multiplier. The game contains 54 trainers of which 18 are currently obtainable — but the community wiki only documents 5 of them in full, and those are the rows below. We are not going to fill the gap with guesses.
| Name | Location | Price/Requirement | Obtainable | Bonus |
|---|---|---|---|---|
| Mike | Trainer Shop | 100$ | Yes | +20% Muscle Growth |
| Lina | Daily Rewards | Day 2 Reward | Yes | +20% Stamina Growth |
| Jenny | Trainer Shop | Rank 2, 5K$ | Yes | +20% Competition Bonus |
| Rock | Trainer Shop/Robux Shop | 699R | Yes | +100% Muscle Growth |
| Sweatmax | Daily Rewards | Day 4 Reward | Yes | +20% Luck Bonus |
- Percentages are the trainer's own bonus and stack with your pets.
- Trainers listed as not obtainable came from past events and cannot be bought now.
- The wiki records 54 trainers in total; only 5 have complete entries.

Common questions
How many trainers are there in Gym Star Simulator?
5 are documented here, listed with location, price/requirement, obtainable. That is every entry our source records — where the game contains more than the community has written up, the table above says so rather than guessing at the rest.
Where do these trainers numbers come from?
They are compiled from Gym Star Simulator Wiki (Fandom), last read Aug 25, 2026. Community sources are written by players and can be out of date, so this page names its source instead of presenting the rows as official.
How often is this trainers list updated?
The page is rebuilt every day, and an automated sweep checks the source five times a day for changes. The figures beside the game's name at the top of this page were read on Oct 13, 2026.
