Pokemon D/P Leveling?

Question

I need to get some weak pokemon 33-45 to lvl100

Whats the best way to train?

Answer 1

I got my torterra to like level 50 by battling a little west of sunyshore city in a grass patch by a guy with purple hair. But then where i usually train now is the sandstormy place right after route 228. Then theres pokemon league. But a great place is spring path right down from veilstone. You should see a kind of square place not to far above and to the right of a lake and thats the place. Its not to hard to find if your looking for it. generally golducks and the evolution of hoot hoot( i forgot the name). Also helps if you have a lucky egg (boosts experience points gained- found on a chansey. 5% you find a chansey with one. Helps if you have a bannette with frisk. you can find bannete after the sandstorm place at night.  Just an idea

Answer 2

Well, train at the Pokemon League ! They're the strongest Pokemon Trainers there are in Sinnoh! plus if you give an Amulet Coin to one of the Pokemon you're fighting with you get twice as money!
