Kayla Itsines

Wikipedia

Kayla Itsines is an Australian personal trainer and entrepreneur who became one of the first genuinely global fitness figures to build an audience through social media rather than through television or publishing. Her Bikini Body Guides, short high-intensity circuit workouts designed to be done with minimal equipment, spread through Instagram before being folded into the Sweat app she co-founded, which turned the programmes into one of the largest women's fitness subscription businesses in the world. She is widely credited with popularising the at-home circuit format much of the industry now runs on.

The scan reflects a small, conditioned frame. At 165 cm and 57 kg with a body fat percentage of 27.8%, the figures describe someone lean and consistently trained without the mass that heavier resistance work would add. The "Hourglass" shape indicates shoulders and hips of roughly equal width around a well-defined waist, the balanced silhouette that bodyweight and circuit training tends to produce, since the load is spread across the whole body rather than concentrated.
