Katie, 27, is a fitness fanatic - so much so that she describes her occupation as a 'Fitness Entrepreneur', as everything she does to make money is based around the exercise industry.
The businesswoman is a personal trainer who creates and markets her own fitness DVDs, and she has also worked as a health and fitness expert for Argos.
As a result, Katie's CV is brimming with accolades, including Fit Pro UK Fitness Professional of the Year 2013.
The hopeful, from Sunderland, says: "In business I'm like a little stealth bomber that flies under the radar and smashes the competition before they've even realised I'm here."
