The Biggest Losers Families went back 20-plus years this week, outfitting slimmer contestants in '80s fitness gear with all the scary trimmings -- big hair, leg warmers, boom boxes. I graduated from high school in 1985, so I recall spending hours leg-lifting with Jane Fonda in P.E. class. A hater of headbands, leg warmers and ankle-high, white leather aerobics shoes, I did adore Flashdance, Footloose and slapping on my new Sony Walkman orange headphones to jog along with Let's Hear It For The Boy. Kevin Bacon, hot. Patrick Swayze, hotter. Have any '80s fitness memories? Send 'em our way in a comment. Back to the show.

All Quiet On The Blue Front -- Of course Vicky's livid her beloved Brady was voted off by swing-vote Amy. In retaliation, a mean-spirited silent treatment ensued. It was fun to witness Vicky eat crow, but she didn't lose enough weight on that diet and was nearly voted off. Trainer Bob tried to dually break the ice and shore up Amy in her quest for the title. The way Amy consistently loses poundage, she's got a real chance.

You Heard It Here - I Predict The Winner Will Be - While many might disagree with Amy's decision not to vote Vicky off at the end of this week's weigh-in, I think it was a smart move. Vicky can't shed weight fast, top-loser Amy will have another crack at her. While Coleen's demise was painful for viewers, her departure sets Amy up for the title if challenge stars align right. Watch out for wild card Ed, he's losing big.

The Biggest Loser Families this week was a treasure chest of diet and nutrition advice sandwiched between soap opera cookie scenes devoid of any nourishing inspiration. Soap star Vicky continued her mean streak when she incessantly insulted Phil -- didn't you love it when Trainer Bob called her "maniacal" and the "biggest game player" ever? But onto the diet, nutrition and more motivational aspects of the show.

Bye-bye teams, we're back to singles with a twist -- eliminated contestants sauntered their thinner bods back to the ranch this week to compete in a challenge for one return spot. Fastest player scurrying up and down a single step 1,000 times was Heba's less-big guy, Ed. Suspense cranked up as Stacey nearly overtook him, delivering the show's first lesson -- Second Place can be just as good as First Place. You may not have the best physique in the gym, the lowest resting heart rate in the running club or the Proudest Warrior in yoga class, but fighting hard at your diet/nutrition best is a winning philosophy.

The Biggest Loser Families continued this week with a two-hour episode featuring the longest challenge in the show's history -- climbing up and down a mountain from sunrise to sunset. Besides being all-day mountaineers, the game took a turning point as contestants were assigned individually to Blue (Trainer Bob) or Black (Trainer Jillian) teams by Heba. She walked into the captain's role by eating a couple glazed donuts in a pitch black room -- whoever ate the most calories was awarded power to choose the teams. Heba played a good strategy -- those donuts swamped Phil's two peanut butter cups and Amy's brownie for top spot, while the rest chose inaction, swallowing nothing.

To me, the best part of the game is watching the contestants drop the weight. Ater five weeks of intense workouts and stellar eating habits, you can't miss dramatic body changes. Player strategy is critical now, but mental and physical fortitude are two wild cards that can swing the game. Here are a few fitness and weight loss lessons from Week Five:

You don't have to be happy to work out hard and lose weight: A cohesive team is powerful, but Heba proved you can still lose weight even when relationships are dicey. Heba made enemies when she resentfully sent peanut-butter-cup-thief Phil to the Black team, but she still lost an amazing eight pounds anyway. Michelle, enmeshed in her parents' divorce, is lighter by seven pounds even with a heavy heart. She nearly fled the ranch, but good 'ole Jillian's been investing major psychological energy to keep her in the game.
