Sure, it's always funny to see Fit Club's overweight (and often underemployed) stars step on that silly, Jolly Green Giant-size scale. But this season inspires more sympathy than laughs, mostly because of the four moms who signed on not just to lose baby weight, but to live longer for their kids. "I want to be the best that I can be for her," says tearful former Baywatch babe Erika Eleniak of her infant daughter. Fit Club itself is certainly in the best shape it's ever been. With motivated, supportive Club-mates like Carnie Wilson, The Sopranos' Vincent Pastore and Family Ties' Tina Yothers, Eleniak will be back in that red bathing suit in no time.
