Congratulations on finding out about EV training! Or maybe your just confused...? Either way I will try my best to help out.
EV is short for Effort Value. Every time your pokemon wins a battle and gets
experience it gains an EV point in specific stat. It all depends on what kind of Pokemon you are fighting to gain EVs in a specific stat.
Okay, so each pokemon gives a point. What do these points do? Well, when you
get four in a single stat, that stat will increase by one extra when you level
There are limits to how many EV points you can get, and this is why people EV
train. Altogether, you can only have 510, and a single stat. Using EV points, you can give two stats a bonus of up to 63!
Also, just to save you some time, I will tell you that you should only put 252
EV points in to a stat, even though you can put three more. Why? Because 252
is the largest number divisible by four that goes in to 255. So you would waste
3 Evs. Unfortunately, you can not stop some waste, and the EV spread people use
the most is 252 in one stat, 252 in another, and 6 in the last. This has the
minimal amount of waste.
So I have to fight 252 of a certain pokemon... ok... that sounds like a lot.
Well I have some good news for you! There are ways to speed this up. There is
a rare condition your pokemon can get called POKERUS. This does not harm your
game or your pokemon in any way, it actually doubles the rate you earn EV points
at. There is also an item called the MACHO BRACE that double them again. So
each point is actually worth four. Saves a lot of time, right?
There are also the power items that you can buy at the battle tower. Each item adds four to the EVs you would already be getting.
So if you fight a magikarp, and have the power item for speed, you get five EV
points. In case you have the POKERUS at the same time, you add first then
double. So these are even faster then the MACHO BRACE.
The power items are:
_____ _____ _____ _____
/ Name | Stat \
| Weight | HP |
| Bracer | Attack |
| Belt | Defense |
| Lens | SP Attack |
| Band |SP Defense |
| Anklet | Speed |

Okay, so it is a horrible box, give me a break, it's my first one! At least
it's easy to read, right?
Another thing that can shorten your training is the vitamins that you can buy on
the second story of the mall. They give 10 EV points in their stat. It's easy
to figure out which stat, just check with the description.
If you ever wanted to take EVs away, just use the berries. They are easy to
identify for the same reason as above. They will take away 10 EV points, or if
you have more than 100, they will lower them to 100. If you have no idea about
the EV's of a pokemon, 11 berries will always lower them back down to zero. I
would just save first, so you aren't wasting berries.
"Always aim high :]"
