Which muscle is listed as stabilization muscle for the core besides Rectus Abdominis?

• A. Gluteus Medius
• B. Latissimus Dorsi
• C. Quadriceps
• D. Deltoids

Answer: (A)

Stabilizing the midsection during movement comes from muscles that hold the spine and pelvis in alignment. The gluteus medius helps keep the pelvis level in the frontal plane, especially during single-leg activities or when weight shifts. By maintaining a stable pelvis, it supports overall core stability and protects the lower back, working with the deep abdominal muscles like the transverse abdominis. The other muscles listed don’t primarily serve this pelvis-stabilizing role: latissimus dorsi is mainly for trunk extension and shoulder movement, quadriceps focus on knee extension, and deltoids move the shoulder. So the gluteus medius best fits the role of a stabilization muscle for the core besides the rectus abdominis.
