Who are the fitness models in the insanity workout dvd infomercial?

There are two girls shown working out in seperate living rooms. Who was the girl in the red top and black shorts? Who was the blonde girl in the blue top with the shredded abs?
I'm not talking about the fitness models working out with Shaun T. at the location where they do the exercises. I'm talking about the two fitness models, one is the brunette with the red top and black shorts and the other is the blonde girl with I think is a light purple top and blue shorts, and has RIPPED abs. They are the ones working out at their homes, unless of course it's NOT their homes and they're just working out at somebody else's home to shoot the infomercial. Who are those two girls?
