I’m not exaggerating when I said Kayla Itsines’ BBG workouts changed my life. I discovered them when I was in my early twenties, fresh out of college and I was unhappy with my body. I’d suffered from an eating disorder for most of my teens and had spent the past few years like many students do — eating and drinking what I wanted, without much concern about my health. I followed Australian trainer, Kayla on Instagram, and, at the time, it seemed like all of the girls in my work gym were following her Bikini Body Guide (BBG) workouts, so I bought the 12-week course, downloaded the PDF (welcome to the world of fitness before the best workout apps were invented), and got going.
