'Shedding for the Wedding' (Wed., 9PM ET on CW) combines elements of 'The Biggest Loser: Couples' with 'Bridalplasty': The couple that wins each week's physical challenge gets one element of their dream wedding (nay plastic surgery).

And the engaged couple that together loses the most weight by the end of the competition wins the ultimate prize: their free (and televised) fantasy wedding.

In the premiere episode, host Sara Rue offers up the first challenge -- a dance-off of sorts. Each of the nine overweight couples must bring their combined heart rate up to 225 beats per minute during the first song. "We will be raising that heart rate higher and higher" with each dance number, Rue explained, and ousting those who don't measure up.

At 325 BPM, Taylor pushes herself so hard she starts to retch. But it isn't enough for she and Peter to stay in the fight dance. Another team wins the challenge, and is rewarded with the free wedding-day attire of their choosing.
