Sophie Moise
Coach
Sophie has always been into sport from an early age, preferring to be ok at everything than very good at one thing. Spending a lot of her 20s travelling and whilst working as Cabin Crew decided to study for her Personal Training Qualification. Qualifying in 2018, Sophie took her first job in the industry as a spin instructor moving on to F45 and then to Third Space where she worked as an Instructor and Group Exercise Manager. In 2019 Sophie discovered and fell in love with CrossFit, finally finding a sport where she could use the ‘jack of all trades master of none’ skill set. She made the decision to do her CrossFit Level 1 in 2021, so she could share the sport and inspire others.
