In which plane does Pulling Straps 1 produce shoulder extension?

Pulling Straps 1 is an exercise that primarily engages the muscles responsible for shoulder extension, which occurs in the sagittal plane. The sagittal plane divides the body into left and right halves, and movements in this plane include flexion and extension. In this exercise, as the arms are pulled back, the shoulders extend, which involves the backward movement of the arm in relation to the torso.

Understanding the importance of the sagittal plane in this context helps clarify how the muscles—specifically the latissimus dorsi, teres major, and posterior deltoid—are activated during the pulling action. This exercise is not performed in the frontal plane, which involves movements like abduction and adduction, nor in the transverse plane, which deals with rotational movements. The term "dorsal" does not refer to a plane of motion; rather, it relates to the back side of the body, making it irrelevant in this context. Thus, it's clear that Pulling Straps 1 effectively exemplifies shoulder extension within the sagittal plane.
