Two players visit home with their trainers in tow, and their weights alone count at the weigh-in. Elsewhere, the teams compete in an obstacle course in order to receive letters from loved ones for Valentine's Day; the players at the ranch must fend for themselves, though one contestant turns to nutritionist Rachel Beller for help preparing a special meal.

The contestants go home for 18 days and have a chance to earn immunity if they lose five percent of their body weight. While some struggle to stay on track, others benefit from the support of family and friends. Also: a home rowing challenge earns the winner $10,000.
