Verified step by step guidance

Understand the anatomical position: The anatomical position refers to the body standing upright, facing forward, with arms at the sides and palms facing forward. This is the standard reference point for describing movements and muscle engagement.

Define pulling motions: Pulling motions typically involve moving an object or body part closer to the body, often requiring contraction of muscles responsible for extension or retraction.

Identify the muscle groups involved: Posterior muscle groups, located on the back side of the body, are primarily engaged during pulling motions. These include muscles such as the latissimus dorsi, trapezius, rhomboids, and erector spinae.

Explain the role of posterior muscles: During pulling motions, posterior muscles contract to generate force and stabilize the body. For example, the latissimus dorsi is heavily involved in pulling actions like rowing or pull-ups, while the trapezius and rhomboids assist in scapular retraction.

Compare with other muscle groups: Anterior muscle groups (e.g., pectoralis major) are more involved in pushing motions, while medial and lateral muscle groups are not predominantly engaged during pulling motions. This confirms that posterior muscle groups are the correct answer.
