A new all-star cast of celebrities, featuring Bobby Brown, Nicole Eggert, Kevin Federline,and in a shocking twist, Kevin's ex, and baby mama, Shar Jackson, arrive at CFC to experience the most brutal celebrity workout on television. Jay McCarroll (Project Runway) surprises himself by reaching new heights as Tanisha Thomas (Bad Girl's Club Season 2) gets up Drill Instructor Harvey's grill... big mistake. Plus, an emotional weigh-in ceremony reveals the extra pounds and emotional baggage the cast hopes to shed at Fit Club.

A simulated beach raid puts the cast on the wrong side of Harvey's water cannon as Kevin and Bobby burn some calories... and lose their pants. An emotional and tear-filled bonfire helps say goodbye to old baggage. Later, Bobby Brown parties hard... and pays the price. Probably not the best way to impress the panel.

Bobby Brown threatens to check out when a "prison break" challenge complete with fierce guard dogs triggers his "fear response." Can Harvey get him to man-up and face his biggest fears? Nicole Eggert gets a big wakeup call on the scale.
