Raleigh, North Carolina--Crossfit NC
This is a Crossfit gym w/ a MMA team, Gracie Jiu-Jistu, Mauy Thai, and some Hapkido.
For those that haven't tried it, the Crossfit workout is a kick in the ass. It's tough. The MMA team (Team R.O.C.) all train it, and it works. I've seen absolute beginers to professional fighters do the workout, and they all love it. I would highly recommend it.
The Jiu-Jistu classes are taught by two Royce Gracie Brown Belts. They both seen highly qualified and are great teachers. Both of them are also really nice guys and easy to learn from.
I haven't trained either the Mauy Thai or Hapkido, but all of the MMA team trains Mauy Thai there, and the team is pretty bad-ass...so that has to count for somthing.
For what it is worth, and from my experiences, I would highly recommend this school to anyone who is interested in either a good workout or learning some good Jiu-Jitsu. The atmospere is very laid back, but serious....and the calibur of training partner is outstanding.
