When Isla Greenwood discovers a nude photo of herself online, she immediately knows her ex-boyfriend is to blame. Worried that her family and work colleagues will discover its existence, she withdraws from everyone and turns to food to suppress her emotions. Twenty-five kilos later, Isla has hit rock bottom and realises she needs the help of her fitness model cousin, Grace, to help get her back on track. But when Grace is injured, Isla finds she lacks the skills and motivation to continue her fitness regime on her own. Fortunately, another saviour arrives in the form of Wes, a cute local personal trainer who convinces Isla to check out his gym. Before long, Isla is rocking her new lifestyle and on the road to getting her old self back. But nothing worthwhile ever comes easy, and she soon finds herself battling a whole new set of challenges, including a rival at a competing gym, an increasingly stressful job, and her deepening feelings for an unpredictable Wes. Will Isla ever resolve the chaos in her life and come out the other end healthy, happy and sane? She sure hopes so.
