Teaching Precautions

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

  • Acute Lumbar Disc Herniation: Avoid end-range spinal flexion under load; keep the reach short.
  • Low Back Pain: Keep the spine scooping and stop if the low back aches.

Setup Instructions

Sit tall on the short box with the legs extended and the feet flexed toward the footbar.

Execution Instructions

Reach the hands up and over toward the toes, peeling the spine down and scooping the abs, then roll back up.

Teaching Cues

Articulation

"Round over the spine as you reach β€” do not fold at the hips."

Breath

"Exhale as you reach toward the toes."

Control

"Scoop the abdominals and keep the shoulders down."

Modifications & Progressions

Straight Legs (Progression)

Keep the legs straight and reach past the toes for more length.

Bent-Knee Shorter Reach (Regression)

Bend the knees to reduce hamstring demand and reach shorter.

Hands on Shins (Injury Modification)

For a disc-sensitive back, keep the knees bent, slide the hands down the shins and stop the reach before the spine rounds under load.
