Steve Halsall started working as a freelance personal trainer 17 years ago. His clients range from business executives and UK companies to celebrity clients and top Hollywood directors in L.A.

"I saw a direct link between the fitness success of my clients and the success of their careers. By finding their weakest link in their mind and body, I was able to simultaneously increase my client's happiness and accelerate their careers at rapid speed. I began Fitness 12 Retreats in 2005 to give my clients a longer, more intensive period of exercise, nutrition and life coaching in one experience. The connection between mental and physical wellbeing is key. We focus on each member of our party with extensive detail and planning."
