Colette McShane

Colette, our Australian Senior Regional Master Trainer, is a fitness fanatic and busy mum who created The HIIT Mum brand shortly after giving birth to her daughter in 2012.  Leaving a corporate career to focus on her love of fitness, Colette proved it is possible to get fit fast, with short workouts and healthy eating.  Colette is changing the lives of thousands of people on a weekly basis by offering classes across Melbourne, at The HIIT Factory, and through HIIT Mum to name a few of her several social media channels.  Colette became a Master Trainer with Fatburn Extreme in 2016 and was recently appointed Senior Master Regional Trainer, together with Gary Arnstein.  She is an inspiration to all instructors!
