In the third video of the series, Underwood and Iwasaki shift the focus to the lower half of the body, using simple screens to uncover how the hips and ankles express coiling and uncoiling. Through movements like the straight leg raise, single-leg stance, reverse lunge, and dorsiflexion test, they show how these assessments reveal not just range of motion, but the strategies and compensations athletes use to get there. Rather than isolating a single joint or muscle group, the emphasis is on understanding coupled motions and how flexion and extension strategies interact across the kinetic chain. As the screens progress, a consistent theme emerges: imbalances in coiling and uncoiling, often more pronounced on one side, can directly influence performance in sport-specific tasks like sprinting, cutting, or kicking. Learn how to improve programming by not just fixing a joint, but addressing movement patterns to build efficiency and resilience.
