Which type of stretch does the Neck Pull aim to accomplish?

The Neck Pull primarily aims to engage and strengthen the abdominal muscles while simultaneously encouraging spinal articulation and alignment. While the exercise does involve recruiting various muscle groups, its primary focus is not on stretching, particularly not on targeting the hamstrings directly. Instead, the Neck Pull promotes flexibility and strength throughout the spine and core, with the intent of enhancing control and stability in the pelvic region and lower back.

When considering other options, the Neck Pull does not directly target the back muscles for a stretch, as it involves spinal flexion rather than extension. Similarly, it does not specifically stretch the hip flexors; while the position may involve some activation of these muscles, the primary action of the Neck Pull is not towards stretching them. Lastly, the exercise does incorporate some elements of chest opening as the arms move, yet this is more of a byproduct of the overall movement rather than the primary intention.

Overall, the Neck Pull focuses more on core strength and spinal mobility rather than on directly stretching the hamstrings or any of the other muscle groups listed.
