Week 4

S13 E4: The stakes are high this week as the red and black teams compete in a fierce battering ram challenge that will give one team exclusive rights to the gym, while the losing team has to find other creative ways to burn calories. Both trainers - Bob Harper and Dolvett Quince - struggle with certain contestants who they feel aren't giving it their all, making it tougher for both teams to get the weigh-in win each one wants. Alison Sweeney hosts the series.
