Aggressive Goals, Aggressive Workout

S1 E3: For Lacey and Allen, weight problems run in the family. Allen's father needs bypass surgery soon, and Lacey's overweight mother died when Lacey was just 16. She wants to lose 60 pounds, and he wants to lose 100, but aggressive goals require an aggressive workout. When their first workout pushes them right up to their physical breaking points, things look almost impossible. With a lot of hard work, they just might be able to beat both these goals and the 500-mile walk down the wedding aisle.
