T13, E13: To address the excuse "exercise is boring," trainer Dolvett Quince spices things up by taking contestants to a Zumba class, and trainer Bob Harper takes the players mountain biking. In this week’s pop challenge, the seven remaining contestants try to load boxes of food on to seven trucks, with the contestant who finishes first getting the chance to pay it forward by donating the products to their hometown food bank. Then a cooking challenge that begins at the market and ends at the ranch, finds the contestants racing against time to whip up a healthy, tasty and creative dish. Their judges will be season 12 fan favorites Antone, Becky and Vinny, who stick around to get better acquainted with the contestants before another weigh-in and elimination sends a player home. Alison Sweeney hosts the series.
