The key to level a gym is to fight with a weaker pokemon. If you use a 1300 vs 700 or 800 it's 100 per win. 600 vs 700 will net 550 ish prestige.
So beat a gym with a weaker pokemon. Right on gotcha will be leveling some gyms.
Do you also get more exp doing it that was as well? Every gym I beat I reviewed
150exp from beating 1 pokemon
250 exp for 2 pokemon.
Never fought another gym with more than 2 actually.
