Gyms are where the three teams fight over territory in Pokémon GO, and they’re the only way to earn PokéCoins without spending real money. This guide explains the system: what a gym is, how to take one from a rival team, how the motivation mechanic underneath it all works, and what raids and Gym Badges add.
The gym system here is the one introduced in the 2017 rework and still in place today. Two follow-up guides go deeper on the parts most players act on: how to defend a gym and earn PokéCoins and which Pokémon make the best gym defenders.
What a Gym Is
Most map landmarks are PokéStops — you spin them for items and Field Research. Gyms are the larger towers. They do everything a PokéStop does, and they also host battles and raids.
A gym is controlled by one team at a time and holds up to six defending Pokémon. Beyond team warfare, a gym lets you join Raid Battles, spin its Photo Disc for items, build a Gym Badge for that location, and earn PokéCoins.
Picking a Team
At Level 5 you choose one of three teams. The choice sticks unless you buy a Team Medallion from the shop, which is expensive, so it’s worth thinking about:
- Team Mystic (Blue) — led by Blanche.
- Team Valor (Red) — led by Candela.
- Team Instinct (Yellow) — led by Spark.
Your team is what the whole gym system runs on. You can only add Pokémon to gyms your team already controls. To take a rival gym, you defeat its defenders to turn it neutral (grey), then claim it for your color.
The Rules, Confirmed
These are documented in the official Help Center and in-game:
- A gym holds a maximum of six defenders, and no two can be the same species.
- You can only place Pokémon in a gym your team owns.
- Legendary and Mythical Pokémon cannot defend (they can still attack). Shadow Pokémon can defend.
- You earn 1 PokéCoin per 10 minutes a Pokémon defends, capped at 50 per day, paid only when the Pokémon is knocked out. (Full breakdown in the PokéCoins guide.)
How to Take an Enemy Gym
Beating a gym means draining every defender’s motivation until they’re all knocked out.
- Find a rival gym. Look for a tower in an opposing color. One with defenders at full motivation takes more work than one that’s already decayed.
- Enter and pick your six. Tap the two clashing pokeball icon to set up your team. The game auto-selects a party, but it leans defensive. Manually choosing attackers that counter the defenders’ types clears the gym faster.
- Fight defenders in order. You face them oldest-first. Tap for Fast Attacks; fire Charged Attacks when the energy meter fills.
- Wear down motivation. Each defeat lowers a defender’s motivation, which lowers its CP. A defender at full motivation takes about three rounds to remove; one that’s already decayed can take one or two.
- Claim it. Once every defender hits zero motivation and is knocked out, the gym turns grey. Tap it and deposit one of your Pokémon.
Type effectiveness matters more than raw CP. For example, a full-motivation Blissey is a Normal-type wall that shrugs off most attackers — but lead with a Fighting-type like Machamp and the same Blissey folds in roughly three rounds instead of dragging on. Use Ice against Dragons, Electric against Flying, and watch for the yellow flash so you can swipe sideways to dodge heavy Charged Attacks like Hydro Pump. If friends are with you, attacking the same gym together drops motivation on multiple defenders at once and can flip a gym before the owners react.
How Motivation Works
Every defender has a motivation meter, shown as a heart above its head. It’s the mechanic the whole gym system rests on.
- It decays on its own. From the moment a Pokémon is placed, motivation starts dropping over time. Community testing has found the decay scales with the Pokémon’s max CP — high-CP Pokémon lose motivation noticeably faster than low-CP ones. That’s why a maxed attacker often makes a worse long-term defender than a bulky, lower-CP one.
- Lower motivation means lower CP. A defender deployed at full sits at about 90% motivation to start, and as motivation drains its effective CP drops with it, making it easier to defeat.
- Berries restore it. You and your teammates can feed Razz, Nanab, or Pinap Berries to top a defender up. A Golden Razz Berry restores it to full instantly, regardless of how low it was.
The practical side of keeping a defender topped up — remote feeding, distance penalties, and feeding limits — is covered in the defending guide.
Raids at Gyms
Every so often a gym pauses normal battles to host a raid. A Raid Egg appears on top with a countdown; when it hatches, a Raid Boss occupies the gym for about 45 minutes. During that window the gym is a cooperative arena only — trainers team up locally or with Remote Raid Passes to beat the boss for a shot at rare, Legendary, or Mega Pokémon.
Defenders aren’t lost during a raid. Their motivation is frozen for the duration — it doesn’t decay and can’t be fed — so when the raid ends, the gym returns to exactly the state it was in.
Gym Badges
Every gym you interact with builds a badge for that specific location, tracked in your Trainer Profile. Badges climb four tiers: Basic → Bronze → Silver → Gold.
You earn Gym XP toward the badge through several actions. Community documentation puts the values at roughly: placing a defender (100 XP), defending (1 XP per minute), feeding a berry (10 XP), winning a raid at that gym (1,000 XP), and defeating a defender (XP scaled to its CP). Raids are far and away the fastest route to Gold — around 30 raids at one gym will do it.
The payoff: spinning the Photo Disc at a gym where you hold a Gold Badge gives extra items per spin, often more Ultra Balls, Max Potions, and Revives.
Knowing Which of Your Pokémon Are Worth It
Gym play comes down to which of your own Pokémon are worth committing — the bulkiest Blissey to sit in a slot, the best-IV attackers to power up for clearing one. That’s not obvious from the summary screen, where IVs and battle ranking aren’t shown at a glance, and checking them one at a time across a full storage is slow.
A tracker like GoDex helps here: scan a catch screenshot to read its CP and IVs automatically, and check how a Pokémon ranks before you sink Stardust into powering it up — so the Pokémon you send into gyms are your genuinely best specimens, not whatever had the highest CP number.

- Best gym defenders — which Pokémon actually waste an attacker’s time, and what to avoid.
Key Takeaways
- One gym, one team, six defenders — and never two of the same species.
- Counter types when attacking. Type matchups clear gyms faster than raw CP.
- Motivation is everything. It decays over time (faster for high-CP Pokémon) and drops CP as it falls.
- Raids freeze the gym. Defenders and motivation return exactly as they were.
- Raid for Gold badges — the fastest path to bonus item drops when you spin.
