Rihanna Bares It All In Spicy Sheer Thong From Savage X Fenty

When Kayla Itsines first uploaded the PDF of the first Bikini Body Guide (better known as BBG) in 2014, Itsines was a 22-year-old personal trainer in Adelaide, South Australia, running exercise classes on the beach. Now 32, Itsines still calls herself a trainer, but that’s kind of like calling the pope a priest: not exactly wrong, but it doesn’t really capture the scale of their work. Itsines currently has 16 million followers on Instagram. That’s roughly the populations of Greece and Norway combined. In 2017, Forbes named her the most influential fitness star in the world, and pre-pandemic, her in-person bootcamp workouts sold out stadiums across the globe.
