I (and my clannies) have pushed to champion 2 ways
One is...by winning a ton and staying online the whole time, I did it in less than 12 hours going from 2900 to 3200. I didn't log out once until I got kicked from game.
Two is..getting a good, smart, defense base. Go on defense as soon as heros are awake. When you win a defense you win 20-30 trophies, when you lose you lose 5-10. Still profit. The downside is you don't earn any loot and at the end of day you will lose pretty much all your resources. But if you have max defense and LvL 9 walls, AND a good defense base that is not common, smartly designed, it will take you there.
