Karina Irby

Founding cheeky-cut swimwear line Moana Bikini in 2011, Karina then went on to launch Bikini Body Burn in 2015 with her trainer Simon McDermott – creating guides that help educate girls on how to build lean muscle and eat a nutritionally-balanced diet. Since the Bikini Body Burn journey started, hundreds of thousands of girls from across the globe are now a part of the family.

Karina uses Protein World products as part of her healthy lifestyle and chooses to take the Slender Blend post workout as this is a high protein low calorie shake. Try her lower body workout to tone up your booty!
