When EV training my pokemon What pokemon should I fight more to raise my defence stats?

Question

I want a high def and sp.def,

Answer 1

Where:    Oreburgh Gate, Left of Oreburgh City

Who:      Geodude (1)

Comments: I think this is the first place in the game you can get defense EV?s.

Could be wrong.

Where:    Oreburgh Mine

Who:      Geodude (1) Onix (1)

Comments: I think it is a bit better than the above one, and mere seconds away,

so why not use it.  Still, there are better places.

Where:    Ruin Maniacs Cave

Who:      Hippopotas (1) Geodude (1)

Comments: Works Fine, I don't think there's anything to run away from...

Where:    Iron Island Mines

Who:      Graveler (2) Onix (1) Steelix (2)

Comments: This one is pretty good, I like it, and you almost always run into

Graveler.

Where:    Snowpoint Temple

Who:      Graveler (2) Onix (1) Steelix (2)

Comments: I think you need a floor other then the first for these to appear.  

You need to run from Sneasel and Golbat, or you can train speed too, though I

don't know why you would need defense AND speed, but, whatever.  At least these

guys are higher level.

Answer 2

i would say fight geodude to raise your defense. Lots of places to find them. But i would use the orebourough mine because lots of geodudes there and a few onixs.  or ruin maniacfor geodudes.

then you could surf up and down victory road and fight peliper. They give out two defense

special defense  would be surfing up and down victory road to fight tentacruel

victory road would be best because you will only encounter tentracruel and pelliper aside from the occasional mantyke
