Which muscle is a stabilization muscle of the core?

• A. Latissimus dorsi
• B. Gastrocnemius
• C. Rectus abdominis
• D. Multifidus

Answer: (D)

Stability in the core comes from deep, segmental stabilizers rather than the big movers. The multifidus sits along the spine as small deep back muscles that attach to adjacent vertebrae and actively resist unwanted movement, providing spinal stiffness and maintaining a neutral position during movement and load. This contrasts with the rectus abdominis (a superficial flexor), the Latissimus dorsi (a large back/arm mover), and the Gastrocnemius (a calf muscle). So the multifidus is the stabilization muscle of the core.
