ATG Split Squat (Ass to Grass)

Step into a deep split squat stance, driving the front knee over the toes until the front hamstring fully covers the calf, keeping front heel down, back knee off the floor, and back leg straight with glute squeezed. Key points: - Front hamstring must completely cover the calf - Keep back leg straight with back knee hovering above the floor and glute flexed - Elevate front foot or use hand support to scale down mobility demands Common mistakes: Letting the back knee collapse to the floor or cutting front knee flexion short.
