OK you will think you need to boost or be good to get this acheivement because most people are destroying you online.. but just keep playing untill you find someone you have control over, there will be people worse then you. when you find someone your pretty sure you can beat, just let them knock you down a couple rounds, then come back and tear them up. if you end up losing because your to damaged, send them a friend request. most bad players are eager to make friends. And im not good at this game, i was just better then a few people.
As far as just getting up the second time, it just takes some patience/practice. I had probs but did it after getting up slow and easy. Just take it slow and easy :)
