View source for Gym

A Pokémon '''Gym''' (Japanese: '''ジム''' ''Gym'') is a place where [[Pokémon Trainer]]s go to train their {{OBP|Pokémon|species}}. Just like real life {{wp|gym|gymnasium}}s, where one can go to work out and build physical strength, Pokémon Gyms are places where Trainers can go to sharpen their {{pkmn|battle|battling}} skills and where their Pokémon can go to gain [[experience]]. Often specializing in a particular [[Elemental types|elemental type]], Gyms create an environment which allows Trainers to test both their skills and Pokémon against those of others. The most powerful Trainer in a given Gym is called the [[Gym Leader]], whom the lower-ranking members of a Gym look up to greatly. In the games, there is [[Gym guide|a character]] that stands near the door giving tips on how to beat the Gym's challenges.

==Official Gyms==
Gyms that are certified by the [[Pokémon League]] are vital to a Trainer's Pokémon journey. Leagues are designed so that conventional Trainers must travel far and wide before entering a [[Pokémon League#Types of competitions|League Competition]], as the only way to enter one is by gaining at least eight official Gym [[Badge]]s, and there can only be one official Gym per city.

===In the games===
There are eight known official Gyms in each [[region]].

===In the anime===
In the {{pkmn|anime}}, [[Gary Oak]] reveals that he has more than eight Badges, suggesting that there are more Gyms in the anime than {{player}}s are given access to in the {{pkmn|games}}. Specifically, he has at least ten badges excluding the {{Badge|Earth}}. Before the [[Indigo League]] competition, Ash encounters [[Otoshi]] in ''[[EP073|Bad to the Bone]]''; he owns eight badges, but only shares four in common with Ash. Later in the episode, another {{pkmn|Trainer}} appears with eight other completely different badges. In total, Ash, Gary, [[Otoshi]] and the other Trainer displayed 27 different types of badges prior to competing in the [[Indigo Plateau Conference]], so there must have been at least this number of official Gyms in the anime version of Kanto at the time.

Whilst on her journey collecting badges, [[Sakura]] collected badges from both [[Kanto]] and [[Johto]], so it is unclear what the rules are for competing in championship tournaments.

At the Hoenn Pokémon League Championship, [[Morrison]] is shown to have an eighth badge different from Ash's, suggesting that there are at least 9 official Gyms in Hoenn. Many believe it could be a badge from {{Ci|Slateport}} or {{to|Pacifidlog}}.

During ''[[DP101|Barry's Busting Out All Over!]]'', in the Sinnoh saga, {{an|Barry}} was seen to have a badge that is not present in the games.
Barry was seen with two more unknown badges in ''[[DP163|Fighting Ire with Fire!]]'', two of which also appeared in [[Nando]]'s ownership in ''[[DP174|Last Call — First Round!]]''.

=====Orange Archipelago=====
The [[Orange Archipelago]] also contains its own league, complete with its own Gyms:
*[[Mikan Gym]]
*[[Navel Gym]]
*[[Trovita Gym]]
*[[Kumquat Gym]]

==Unofficial Gyms==
===In the games===
====Saffron City Dojo====
{{Main|Fighting Dojo}}
The Trainers of this Gym specialize in {{type2|Fighting}} Pokémon. It used to be an official Gym until [[Sabrina]] defeated its leader. After the player defeats the Dojo's leader, he will give the player either {{p|Hitmonlee}} or {{p|Hitmonchan}} as a reward.

====Prestige Precept center====
{{main|Prestige Precept Center}}
Also known as the Pre Gym, this unofficial Gym of [[Phenac City]] doubles as an {{pkmn|academy}}. In [[Pokémon Colosseum]], its leader, [[Justy]], will not battle the Trainer until they have at least six Pokémon, and will give away {{TM|27|Return}}.

===In the anime===
====A.J.'s Gym====
This Gym is run solely by the Trainer [[A.J.]], and is notable for its rigorous training methods. It is unknown what prize if any A.J. gave to any victorious challengers, because he left it to enter the [[Pokémon League]] after he defeated 100 challengers in a row using only his {{p|Sandshrew}}. This Gym appears in ''[[EP008|The Path to the Pokémon League]]''.

====Fighting Spirit Gym====
This Gym was run by {{ka|Anthony}}, who was training his {{p|Hitmonchan}} for the [[P1 Grand Prix]]. It did not appear to be used for actual [[Pokémon battle]]s. Instead, it had the appearance of a [[wp:gym|gym]] used for training and exercising.

====Kaz Gym====
This Gym in [[Dark City]] wanted to become an official Gym to earn money, but was rejected by the [[Pokémon League]]. It has Pokémon of various types, but its primary Pokémon is an {{p|Electabuzz}}. This Gym appears in ''[[EP042|Showdown at Dark City]]'' and is run by [[Kaz]].

====Yas Gym====
This Gym in [[Dark City]] wanted to become an official Gym to earn money, but was rejected by the [[Pokémon League]]. The Gym trainers specialize in [[Fighting]] but the Gym Leader's Pokémon is a {{p|Scyther}} a {{type2|Bug}}/{{type2|Flying}}. This Gym appears in ''[[EP042|Showdown at Dark City]]'' and is run by [[Yas]].

====Coastline Gym====
This is an unofficial Gym that was featured in ''[[EP256|Just Add Water]]''. It is located on the outskirts of [[Blackthorn City]]. Led by [[Dorian]], the Gym specializes in {{type2|Water}} Pokémon. Unlike the other Water-type Gyms, Dorian holds his battles underwater.

Although the Gym is unofficial, Dorian is hoping that by word of mouth it will become more popular. In fact, after {{Ash}} and {{Ashfr|his friends}} visited the Gym, they promised they would tell everyone at the [[Silver Conference]] about it. However, it hasn't been mentioned since then.

==Differences among generations==
Until [[Generation V]], the Gyms of each region have a uniform exterior style; the specific styles vary by generation.

==Trivia==
* For ''[[DP008|Gymbaliar!]]'', [[Professor Oak's lecture]] is about Gyms.  He writes this [[Pokémon senryū]] about them: かてるまで　なんどもちょうせん　ポケモンジム ''Kateru made nandomo chōsen, Pokémon Jimu'' "Until you win, battle again and again; that is a Pokémon Gym."
** This is also the episode [[Team Rocket]] set up a fake Gym, with [[Jessie]] acting as its Leader.
* In [[Generation I]], {{DL|List of glitches in Generation I|fishing in statues|a glitch}} allows Trainers to [[fishing|fish]] in the statues at the front of the Gyms.
* No known Gym has specialized in {{type2|Dark}} Pokémon.
* {{game|Platinum}} is the only game where the Gym order is changed from its predecessors, which are {{game|Diamond and Pearl|s}} in this case.
* As the [[Fighting Dojo]] in Kanto was once official, every region except [[Unova]] has had a {{type2|Fighting}} Gym at one time.
** Despite the above fact, there has been a Fighting-type specialist in every region, either as a Gym Leader or an Elite Four member.
** A {{pkmn|Trainer}} in the [[Glitter Lighthouse]] also says Jasmine used to specialize in {{type2|Rock}} Pokémon, meaning every region except [[Unova]] has had a {{type2|Rock}} Gym at one time.
* In {{game|HeartGold and SoulSilver|s}}, each Gym's frame is colored according to the elemental type, except for the [[Viridian Gym]], which has no specialist type. The Viridian Gym's frame is green.
* In {{game|HeartGold and SoulSilver|s}}, [[Walking Pokémon]] are not allowed in the [[Blackthorn Gym]] and [[Viridian Gym]] because the flooring is unstable. 
* In Generation V, six of the eight Unova Gyms serve dual purposes, both as a place of battle and as a service; [[Striaton Gym]] is a restaurant, [[Nacrene Gym]] is a museum, [[Castelia Gym]] is a gallery showcasing the paintings of the [[Gym Leader]] [[Burgh]], [[Nimbasa Gym]] is a set of roller coasters to go with the Ferris Wheel in [[Nimbasa City]], [[Driftveil Gym]] is a mining operation, and [[Mistralton Gym]] is an airfield.
* Both Dragon-type Gyms are the last to be challenged in their respective regions.
* The Rock-type has been the first Gym Leader's specialty for the majority of the regions.
