The HIIT Craze: Benefits and Pitfalls

Kirsty Godso is the trainer behind Olivia Rodrigo, Hailey Bieber and Kaia Gerber. After 13.5 years inside Nike, she became the face of Vuori through a multi-million-dollar brand partnership. She reveals what celebrities actually do to build their bodies, why most high-intensity workouts fail, how she sets goals for clients, the truth about protein products, common keto mistakes, and the red flags hiding in “healthy” foods - plus her take on Alo, Lululemon and why the athleisure industry keeps rapidly growing.
