During the Long Box series, what is a typical cue to protect the lower back during spinal extension?

• A. Engage the abs and keep pelvis stable; avoid over-extension of lumbar spine.
• B. Arch the lower back for mobility.
• C. Hold breath to stabilize.
• D. Increase lumbar extension.

Answer: (A)

The main idea here is to protect the lower back by stabilizing the pelvis and engaging the deep abdominal muscles so that the extension comes from the thoracic spine rather than the lumbar spine. When you extend on the Long Box, you want the movement to be controlled from the torso while the pelvis stays level. Engaging the abs and maintaining a stable pelvis creates intra-abdominal pressure that supports the lumbar area and prevents the low back from arching excessively. This cue helps you keep the spine lengthened and the ribcage soft, so you don’t compress or strain the lumbar joints.

Arching the lower back for mobility pushes the movement into more lumbar extension, which can irritate or overload the lower back. Holding the breath to stabilize isn’t an effective or safe strategy for spinal control, and increasing lumbar extension directly contradicts the goal of protecting the back.
