McMillan frames sprinting and jogging as fundamentally different motor tasks, not points on a spectrum. Jogging lives behind your center of mass with collapsed posture and horizontal force. Sprinting lives in front of center mass, is fully vertical, and demands total-body expressiveness. Sprinters warm up by skipping and slow striding—never by jogging—because skipping shares the same stiffness, coordination, and pop as sprinting itself.
