5th Gen were should i go to level?

I'm trying to train pokemon in white 2, and normally I would just ask for a certain level, but here is my problem with that. I am trying to train a team of all levels, to be official, 1- 60. Though, my goal is to get them all to atleast 80 or higher. So where should I train for levels 1-10, 2-20, 3-30, 4-40, ect? Thank you

Anywhere with Audinos. They give massive EXP and cut your training time down a fair amount. Giant Chasm has the highest level Audinos I think.
