After three weeks of intensive training, the program has begun to take its toll on the clients. After a series of heated exchanges, Jackie challenges the group to meet for dinner to resolve their issues.

Jackie adopts a new method in week four's basic training, sending the team on a three-mile run through Magnolia Park. Later in the week, Jackie takes the clients through an epic firefighter workout, complete with hunky firefighters.

The clients have been away from Jackie for six weeks, struggling to use everything that she taught them to realize their ultimate weight loss goals. The clients' friends and family are brought together for a final reveal and celebration.
