Can girls do mma

Yes. I don't know of any MMA gym that prohibits women from participating. There are some women's professional and amateur MMA fights around the country, although they are relatively rare. Perhaps most notably, EliteXC, the MMA league aired on ShoTime, has women's MMA.

Just adding on to the first guy, Shelby Marxx is a very famous WMMA star, she has many championships if I remember right.
