The core exercise labeled with number 4 targets which part of the body?

• A. The legs
• B. The arms
• C. The trunk
• D. The neck

Answer: (C)

This item focuses on which body region a core exercise primarily trains. The trunk, which includes the torso along with the abdominal and lower back muscles that surround the spine, is the main target. Core exercises are designed to stabilize and support the spine and pelvis, building strength and endurance in this central region to improve posture, balance, and the transfer of force during movement. The legs and arms may be involved for movement or stabilization but are not the primary focus of most core routines, and the neck is not the central target of standard core work. So the trunk is the most accurate answer.
