Go to the sports arena in Nimbasa city as well. They change every day, it says that they change twice but I do not know what times they change sports during the day. Anyway, both arenas have about 10 people to battle, all with level 65-ish Pokemon that can help you level. Some people also give away items, the good ones are the PP Ups and PP Maxes. It's always only the people near the entrance of the field.
Or, go battle the Elite 4 again. All Level 70+ and you get 6 Pokemon per battle, not 2-3 like trainers.
