Effort Values, most commonly referred to as EVs, are one of the most important factors in competitive Pokemon. Unlike nature and IVs, which are controlled basically by luck, rigorous breeding, soft-resetting or RNG abuse, EVs can be directly manipulated by the player on the fly with very few setbacks. The purpose of this guide is to direct the user through EV training in FireRed and LeafGreen, the remakes of the famous and beloved Generation 1 games Red and Blue. Why are these games important? Just as the Hoenn games have their respective guides, it is useful for a player to train his native Pokemon in Kanto to eliminate the need for extensive trading just for EV training. This guide will explain the barebones knowledge of EVs without going into too much detail. A more exhaustive guide on EVs can be found here.
The Source of EVs
All competitive Pokemon players know, or should know, the purpose of EVs. Training an in-game Pokemon to have competitive EVs, however, is much more time consuming than typing a number into a text box on a simulator.
Battling In-Game Pokemon
There are a plethora of in-game trainers and wild Pokemon to battle throughout your adventure. Without any modifiers, EVs are gained 1, 2, or 3 at a time, depending on the Pokemon you battle.
Special Items and Pokerus
If you are discouraged by the prospect of obtaining only at most 3 EVs at a time, fear not; there are a few ways to accelerate the growth of your Pokemon. EV-boosting vitamins can be found in various places on the ground or purchased on the fifth floor of the Celadon City Department Store. These items can be used to elevate a stat's EV to a maximum of 100, 10 per vitamin taken. Unfortunately, as life has taught us, nothing is free; you will be paying $9,800 for 1 vitamin. The maximum number of any given vitamin you can use on one Pokemon is 10, which comes to $98,000 just to get 100 EVs in a single stat! Fortunately, there are vitamins scattered throughout the game, and you will be shown in this guide where these items are.
Late in the game you will find a very helpful item called the Macho Brace, which doubles the EVs earned from defeating a single Pokemon. The Macho Brace can be found after defeating Giovanni once and for all at the Viridian Gym. A second helpful item is the Exp. Share. After any battle, half of the total experience given after defeating a Pokemon goes to the holder, and the rest is distributed to the other battlers. Since experience is gained, a Pokemon holding the Exp. Share also gains EVs. The Exp. Share is found mid-game on Route 15, and you must have registered 50 Pokemon in your Pokedex to obtain it.
The final key to accelerated EV training is the Pokerus. This rare virus doubles the EVs earned from defeating a single Pokemon, which in conjunction with the Macho Brace yields a possible 4, 8, or 12 EVs per Pokemon! Unfortunately, the Pokerus is even rarer than a random shiny Pokemon. In fact, you can only obtain the Pokerus in Ruby, Sapphire, and Emerald, so you will not be able to abuse the virus until after the Elite 4 without trading with another FireRed or LeafGreen game that has obtained the Pokerus by having traded with a Hoenn game itself.
It is extremely important to note that the EV-reducing Berries do not work in FireRed or LeafGreen, so there is no way to delete unwanted EVs unless you trade your Pokemon to Emerald! That, however, is counterproductive to the idea of an in-game run, therefore it is imperative that you get them right the first time. Keep track of them in a text editor or on a sheet of paper.
In-Game Trainer Locations
This is a comprehensive list of trainers you will face throughout your adventure that give dedicated EVs. Of course, there are hundreds of in-game trainers, but a vast majority of them contain a variety of EVs, making it more difficult to plan ahead of time what EVs you wish to obtain.

In fact, they are vital to your success after you have defeated all of the in-game trainers. As you will see, it is much easier to find HP, Attack, and Speed EVs earlier in the game, while defensive and Special Attack EVs are extremely rare until later in the game.
