Teaching Precautions

Common precautions, not exhaustive. Screen every client and refer when in doubt.

Acute Lumbar Disc Herniation: Avoid end-range extension and rocking; keep the lift small and controlled.
Pregnancy: Prone positioning is not suitable after the first trimester; use a wedge, or a side-lying or standing alternative.
Spinal Stenosis / Spondylolisthesis: Sustained lumbar extension with rocking can aggravate stenosis and pars stress; keep the rock small and the lift low.

Spring Tension 1 medium or 1 strong spring

Headrest Down

Transverse Abdominis (Secondary)Hamstrings (Secondary)Gluteus Maximus (Primary)Erector Spinae (Primary)

Lie prone on the long box, reach back and hold the ankles with knees slightly apart and the chest lifted.

Exhale to lift the chest and legs, balancing on the pelvis, and rock the body forward and back over the box with control.
Inhale to release.

Control

"Rock only as far as you can hold the position — no momentum."

Breath

"Exhale to lift and rock, inhale to settle."

Form

"Keep the knees slightly apart and the chest open."

Lift the chest and legs without rocking to build the base strength first.

Increase the arc of the rock as control improves.

For spinal stenosis, lie prone with the hands stacked under the forehead, keep the lift tiny and let the legs stay down instead of rocking.
