Meanwhile, Bob works the contestants out in the mud. This soon turns into messy mud shenanigans, ending with Bob literally being dragged through the mud. Yes, it's payback time. Jillian emerges from the gym and Bob warns her that she's next. She takes off at a sprint, but doesn't make it very far. The other contestants carry her and drop her straight into a mud puddle. She is not happy, and has a giant mud clump in her drawers. Pretty! Jillian promises revenge in the last chance workout!

Speaking of last chance workout, it's here, and Jillian's revenge is upon them. Payback's a bitch, she reminds us. Last chance workout is usually just a generic butt-kicking, she says, but today it's personal. Sunshine wants her to bring it on. She knows that the road to the final four is paved with beatings. Jillian says that she beat them until she thought their brains would pour out of their ears and noses. She beat them and beat them until the pain of the mud went away. And now she feels a little better about the whole ordeal. Drea, meanwhile, is very motivated to make her way from the middle of the pack to the top. She wants to work out like she's worth it. Michael is still the biggest guy there, but he's being conditioned to kick it into fifth gear. He jogs for a mile without stopping and celebrates. Bob tells him to do it again. O'Neal works on his strength, and Bob tells him that he's unstoppable. Michael continues to run, and is on his way to a 5K. Bob yells, "A 372-pound man running a 5K with that big ole' afro! That's right!" Finally, someone talks about the real elephant in the room: Michael's afro. [Why haven't they done makeovers yet? Michael and Daris really need help. -- Angel] Bob says that he's pushing the contestants past any limits they thought they had. Michael finishes his 5K, and Bob says that five miles is next. Remember when Michael was a slacker? No longer! He's really happy about his progression over the weeks. Michael finishes five miles, and says that's the end for him. He's proud, and the others are proud of him. He says he'll never go back to 500 pounds.
