Trying to identify a series I saw a couple years ago. It may have had "battle" in the title. Description: set in a warehouse, no ring, but mats on the ground. 4 girls in sort of teams of two tha traded off. In the beginning of the video they came down from stairs. The interesting thing is that they had like 3 or 4 judges that watched on the side and did some interviews. I think there may have been at least 2 of these titles made. Pretty rough/intense. with maybe some crying. Any of this ring a bell to anyone?
