They are halfway through the competition with no signs of slowing. The first challenge is about luxury vs weight loss. The luxury auction is where each contestant bids on luxury items individually with $500 in Biggest Loser Bucks. The items: A full spa day (massage, facial, mani/pedi courtesy of Burke Williams) and the winning bid can invite someone to join. A one-on-one with Bop Harper at his home. Trek bikes for 3 loved ones (a $4000 value). A KitchenAid kitchen makeover (worth $5000). A trip to the Bahamas for 5 nights with 3 loved ones. A growing pound, which is a one pound advantage for one individual... but every pound you don't use it it grows up by a pound... with a 5 week limit. Fly in a loved one for a night and stay at a the Langham Huntington in Pasadena. The last bid was for a mystery box which turned out to be immunity (weight still counts towards the team but the individual can't be eliminated no matter what). Unfortunately everyone goes all-in for the prizes they want, completely making the rules of an auction irrelevant. (Side note: how pristine is Bob's gym??)

At the last chance challenge the team that wins gets a one pound advantage at weigh-in. Three players will compete for each team and flip a tire 50 ft. Then 50 step ups. Then the other 3 team members will flip and do step ups. Team Jen wins.

Team Jen:
Colby - 282 to 278, down 4 pounds
Luis - 260 to 250, down 10 pounds
Erin - 205 to 200, down 5 pounds
Lauren - 202 to 199, down 3 pounds
Vicki - 205 to 202, down 3 pounds
Toy - 2282 to 278, down 4 pounds

Team Dolvett:
Roberto - 291 to 283, down 8 pounds
Jacky - 265 to 258, down 7 pounds
Felicia - 202 to 195, down 7 pounds
Rob - 278 to 268, down 10 pounds
Stephen - 269 to 259, down 10 pounds

Toy and Vicki are below the line. The person going home is Toy... which is extremely unfortunate because she and Jen decided not to use her one pound advantage from the auction, which would have been beneficial at this weigh-in.

The next challenge is to win a luxury for the entire team... one day on a private yacht AND letters from home. But if they chose the boat, they wont be allowed to use the gym. To win they have to race down the beach and tow a boat, then pull in the buoys and unclip an oar. The first team to reach the finish line wins the challenge. Team Dolvett wins.

Team Jen:
Vicki - 202 to 198, down 4 pounds
Lauren - 199 to 194, down 5 pounds
Luis - 250 to 244, down 6 pounds
Colby - 278 to 271, down 7 pounds
Erin - 200 to 199, down 1 pound

Team Dolvett:
Felicia - 195 to 191, down 4 pounds
Rob - 268 to 262, down 6 pounds
Roberto - 283 to 276, down 7 pounds
Stephen - 259 to 253, down 6 pounds
Jacky - 258 to 251, down 7 pounds

Vicki and Erin are below the yellow line. Erin sings a song she wrote to lift everyone up. Ironically she wrote it for getting below 200 pounds but it was to inspire others, she didn't realize it would be inspiring to her, as well. The person to leave this week at the ranch is Vicki. Although, she promises to be "so hot" at the finale.

When we see a glimpse of Toy and Vicki (total weight loss of 60 pounds) they look fantastic and we can't wait to see them at the finale.
