At the beginning of every fight your opponent will walk to the middle of the ring and raise his hand, (you can not hit any other buttons or he will not raise his hand) when you are in the middle of the ring with him push right on the D-pad and your fighter will raise his hand as well. do that 10 times and you will get this achievement.
(NOTE: you do not need to hit the glove directly, just put you fighters hand up near your opponents)
