This line drawing shows a person standing upright with arms extended horizontally, demonstrating a foundational upper-body mobility exercise. Dotted lines indicate the trajectory of the arms during movement, emphasizing joint articulation and muscle engagement from shoulders through wrists. The posture reflects proper alignment-neutral spine, engaged core, and feet shoulder-width apart-for safe execution.
