What is the function of the abdominals during spinal extension exercises?

The abdominals play a crucial role in providing stability during spinal extension exercises. When the spine is moved into extension, the abdominal muscles engage to create a stable base, counteracting the forces acting on the body. This engagement helps maintain proper alignment and balance, allowing the extensor muscles of the back to work effectively without excessive strain or risk of injury.

In these exercises, the abdominals prevent hyperextension and excessive arching of the lower back by stabilizing the pelvis and lower spine. This tension and support are vital for maintaining optimal posture and ensuring the movement is performed safely and efficiently. By providing this stability, the abdominals help facilitate a more controlled and effective extension, promoting strength and endurance in both the core and back muscles.
