This week the couples size each other up and get cut down to size by fitness trainers Jennifer and Nicky in grueling workouts. Size becomes an issue as the couples try on wedding gowns and tuxedos with wedding planner Brian Worley. The first wedding challenge is a dance-a-thon where the couple's will compete to win their fantasy wedding gown and tux. And one couple triumphs while another is sent packing in a tense "Til Death Do Us Part" elimination challenge.
