Gym
Train adult pets' Attack, Defense, and HP - 5 sessions per pet per day, costs that scale with stats, caps tied to Pet Level, plus streaks, daily challenges, and Gym tickets.
The Gym is where adult pets build their combat stats. Coach Roary runs the floor, and everything you do there feeds into the Pet Arena and the Strongest Pets leaderboard.
Where to find it
- Direct link: /gym/
- Search for Gym.
Who can train
- Adult pets only. Eggs and babies cannot train, no matter how much XP they have.
- The pet must be at home or in a den. A pet away at the Hotel, the Pet Park, or on an Expedition cannot train until it comes back.
The three stations
- Punching Bag trains Attack - more damage dealt in battle.
- Shield Training trains Defense - less damage taken.
- Treadmill trains HP - survive longer in a fight.
Each session gives +1 to +3 points in that stat and 5-25 XP. Training also costs the pet some hunger and health, so keep food handy.
Sessions and rest
- Each pet gets 5 training sessions per day.
- After a session the pet rests for about 1 hour before it can train again.
- Sessions and rest are tracked per pet, so a big stable can keep training all day.
What it costs
Training costs 100 MPC plus 5 MPC per point in the stat being trained, so a stat at 20 costs 200 MPC. Costs rise as a pet gets stronger — building a champion is meant to be a long-term investment.
Stat caps
Every combat stat is capped at 10x your pet's Pet Level. The Hotel training add-on obeys the same cap. A Level 12 pet can train each stat up to 120. When a stat hits its cap, that station is disabled until the pet levels up, so earning XP anywhere in the game raises your ceiling. See Pet Stats Explained.
Health changes everything
Your pet's Health decides how well it trains:
- 90% Health or above: +1 bonus point per session and shorter rests.
- Low Health: 1 point less per session and longer rests.
A quick trip to the Vet before a training run pays for itself.
Training streak
Train at least once a day to build a streak. Every streak day takes 1% off training costs, up to a maximum of 10%. Miss a day and the streak resets to one.
Coach's Daily Challenge
Each day Coach Roary picks one stat to focus on. The first session you complete on that stat earns +50% XP and a 250 MPC bonus. The focus stat is the same for everyone and changes at the start of each day.
Gym charms
Lifetime training sessions unlock charms and one-off coin rewards:
- 10 sessions: Warm-Up, 300 MPC
- 50 sessions: Regular, 1,000 MPC
- 250 sessions: Gym Rat, 3,000 MPC
- 1,000 sessions: Iron Champion, 10,000 MPC
Gym items
- Gym Pass - makes one training session free.
- Extra Rep Ticket - gives one pet a 6th session today.
- Golden Extra Rep Ticket - gives a 6th session and makes it free.
Tickets are limited to one Extra Rep Ticket per pet per day. Using one on a pet does not stop your other pets from using their own ticket that day. Gym Passes have no daily limit. Look for them at the Ticket Counter in Shops, or watch for them with Findley.
Items sitting in your player shop do not count as available — pull them off the shelf before you try to use them.
Stat Treats
The Sports Outlet sells three rare treats that add a permanent +1 to one combat stat when used on an adult pet from your Backpack — no Gym session needed:
- Ironbite Jerky — +1 Attack (400 MPC)
- Shellcrunch Biscuit — +1 Defense (400 MPC)
- Heartroot Chew — +1 HP (400 MPC)
- Champion's Feast (epic, 1,500 MPC, also at EPIC Only) — all three treats on one podium: +1 Attack, +1 Defense and +1 HP in a single sitting, and it only counts as one of the day's treats.
Treats follow the same level cap as the Gym — a stat already at its cap refuses the treat and the item is not used up. Each pet can eat 3 Stat Treats per day, counted across all three kinds. Unlike the Gym, a treat works on a pet that is away at the Hotel, Park or on an Expedition, and it costs no session and no hunger or health. Per point the Gym is still the better buy; treats are for topping up a pet that has used its sessions, or one you cannot get to the floor today.
Training several pets at once
With more than one adult pet, the Train several button above the pet grid switches the page into multi-select. Tick the pets you want (or Select all ready), then pick a station as usual. Each station shows how many ticked pets can train there and the combined price.
Clicking the station opens a checkout listing every ticked pet with its own price. Pets with an active Gym Pass show FREE, your streak discount is already applied, and a pet that is at its cap or still resting is listed but left out of the bill. One confirm trains them all, and the same window then shows each pet's gain, XP and any level-ups. If one pet is refused (for example it ran out of sessions a moment earlier), the others still train.
Passes and tickets work the same way: Assign to several pets in the Gym Items panel opens a list of your pets with a picker next to each. The counters at the top count down as you assign, and pets that already have a pass or used their ticket today only offer what they can still take. Assign your Golden Extra Rep Tickets first, then run the checkout and those pets show up as FREE.
Every pet card also counts down its own rest timer, and after a single session the result window offers Train [next pet] so you can move straight on.
Strongest Pets
The Gym page ranks the ten strongest pets in MiroPets by total Attack + Defense + HP. Your own best pet's rank is shown in the "Your Gym" panel alongside your lifetime sessions, stat points gained, and best streak.
How to train well
- Pick one pet to build rather than spreading sessions thinly — or, if you want the whole roster moving, use Train several so it is one checkout instead of a dozen clicks.
- Feed and heal it first so every session gets the healthy-pet bonus.
- Train the daily focus stat once for the XP and coin bonus.
- Spend your ticket on a pet that has already used all 5 sessions — or feed it a Stat Treat.
- Keep enough MPC in reserve for food and vet care.
Common mistakes
- Training a pet that is away, then wondering why the buttons are greyed out.
- Ignoring Health and quietly losing a point per session.
- Pouring everything into Attack and leaving the pet too fragile to survive a fight.
- Letting a stat sit at its cap instead of earning XP to raise it.
- Saving a Gym Pass so long it expires — passes last 24 hours.
