The range of motion limitations during overhead pressing movements can commonly be attributed to tightness in the latissimus dorsi. This large muscle extends from the lower back to the upper arm and plays a significant role in the movement. When the latissimus dorsi is tight, it can restrict the ability to fully lift the arms overhead, leading to decreased range of motion. This tightness pulls the shoulder and arm down, preventing optimal positioning and allowing for the necessary overhead extension.

While other factors like core stability, triceps strength, and shoulder mobility may also impact overall performance during overhead pressing, the direct restriction of movement overhead is primarily caused by muscular tightness. In this context, tightness in the latissimus dorsi can lead to compensations during the lift that further limit the overall effectiveness and safety of the movement, highlighting the importance of flexibility and proper warm-up in functional training.
