Check out this crazy knockout video

Maggie Hendricks

There are plenty of fun ways to cause a knockout. Throw a front kick, as Anderson Silva did to Vitor Belfort. Use a series of punches, like Antonio Silva did to Alistair Overeem. Perhaps use a big overhand punch, like Dan Henderson has done many times. Or you could do an amazing, acrobatic kick, like the young man in this karate video from Russia did.
