Re: EV Help
If you have questions about EV's, look in the diamond and pearl guides forum. It's a sub-forum in the D/P section. You can find it on the front page. There are EV training and IV breeding guides in it. Try looking around before posting a thread for one question, please.
But, since you did post a thread, I'll explain it. Mostly because I'm bored though. :P
When you go fight a pokemon, say a Bidoof. It gives 1 EV in HP. Give your pokemon the Macho Brace, (use the macho brace, then you don't have to use different items for different stats) it gives 2 HP ev's. More efficient, right? And, if your pokemon has pokerus, that doubles that! So one Bidoof gives 4 HP EV's.
