Jillian visits her team at the gym, and in short order tells Shellay to take her hands off of the treadmill or get a swift punch in the face. Jillian is quite distressed to learn that her team didn't do their "homework," which is extra time cardio when the trainers aren't there. She interviews that she keeps trying to nudge them, but they will not be nudged. She screams that when they all get eliminated one by one she'll make sure the door doesn't hit their asses when they leave, and will then look forward to Season 7 when she gets some people who care. She screams to her team that they're not cutting it, and are worse than any season she's ever trained. She is totally through with this whole "being nice" experiment. She asks her team what's going on, and no one will let out a peep. Jillian is Sick Of It. She interviews that the women on her team want the results but don't want to do the work. If they want to stay, they need a complete overhaul. She tells them in so many words that they suck and points out the door. Amy starts giggling and Jillian tells her to get off of the elliptical and leave. Renee has totally been crying this whole time. Jillian tells her ladies to get their shit together. And with that, we conclude part A of episode four!
In part B: another team will have to make their Sophie's choice and even though it's not shown in the preview I'm guessing Jillian screams some more.
