Which muscle groups are targeted by the spinal twist stretch?

• A. Quadratus Lumborum and Erector Spinae
• B. Latissimus Dorsi and Gluteus Maximus
• C. Hamstrings and Gastrocnemius
• D. Rectus Abdominis and External Obliques

Answer: (A)

When you twist the spine, you’re lengthening muscles that run along the back of the torso and help you rotate and stabilize the spine. The two main muscle groups that get stretched in this position are the quadratus lumborum and the erector spinae. The quadratus lumborum attaches from the lower ribs down to the pelvis and supports lumbar stability and lateral flexion. In a spinal twist, the side of the QL that’s being stretched lengthens as you rotate, contributing to the feel of a stretch along the side of the lower back. The erector spinae runs longitudinally along the spine and is essential for extending and stabilizing the vertebral column. As you twist, these muscles lengthen along the back, especially when the spine is rotated away from their origin points, giving you a stretch along the mid to lower back. Other listed muscles aren’t the primary targets of a spinal twist. The latissimus dorsi and gluteus maximus are more involved with shoulder and hip movements, respectively. The hamstrings and gastrocnemius are in the posterior chain but relate more to leg movement and ankle action. The rectus abdominis and external obliques contribute to trunk rotation, but the stretch aspect of a spinal twist is most directly about the back’s posterior stabilizers. Therefore, the best match is the quadratus lumborum and erector spinae.
