Start out as the Heavyweight class. When ever possible, spar with your sparring partner. After the training match, you can upgrade your attributes. Then what I did was I maxed out my stats on standing strikes punches. Also when you choose to fight some one always choose fighters with Kick Boxing, Wrestling, or Boxing. If you chose a BJJ fighter or Muay Thai fighter, they will take you down and keep you down. Unless your an expert on the ground game, then go ahead and fight them. Since I'm not, I always choose Boxing and/or Wrestling. When the fight starts, land a few leg kicks and then land 2 power punches, keep on repeating and you should get him on the ground for a TKO, or even knocked out. Today I got the achievement, Call me "No Touch!" I went 35-0, so I'm guessing you just have to play 35 matches to get the Hall of Fame Achievement and the Call me "No Touch!" Achievement. One more thing, if you know that you are going to loose to the point where you see your mouth guard on the mat, then press the Xbox Guide and Press "Y" to go to the dashboard. From there, load up UFC 2009 Undisputed, the last save will be after the last sparring session or even sooner depending if you manually saved the game.
