It features Alex Cohen, Ellen's roller derby trainer, "Axles of Evil".
There's a small mention of Whip It, but mainly gives some interesting background on the sport.Cohen has joined forces with another L.A. Derby Doll, Jennifer "Kasey Bomber" Barbee, to write Down and Derby: The Insider's Guide to Roller Derby.
I like this quote which I think applies to Ellen's Babe Ruthless:
It's not all about brute strength and size, though. "If you're a good skater it doesn't matter what size you are," Cohen explains. "People are most intimated by ankle biters" — skaters close to the ground who are very quick and hard to pass. After all, on the track, it's all about speed
