http://www.ikfkickboxing.com/RulesXG.htm Here is a new Kickboxing ruleset called Xtreme Gladiator (XG) Rules. It's a combination of Muay Thai and San Shou. It allows punches, kicks, knees, elbows, throws, and takedowns. What makes this difference and not legal in all US states? They wear MMA gloves. I really would love to compete under those rules.
