Sit tall on the short box with feet strapped securely, spine long and flat, arms reaching forward at shoulder height.

Inhale to prepare, exhale to hinge forward from the hips with a flat back until the torso hovers over the legs, then return tall with control.

Form

"Hinge from the hip sockets — the spine stays one long line."

Alignment

"Reach the crown forward and the tailbone back."

Breath

"Exhale to hinge, inhale to return tall."

Support the trunk with the hands behind the thighs to reduce the hinge load.

Hold the hinge position for two breaths before returning tall.

For low back pain, hinge only a little from the hips with the hands behind the thighs for support, and stop before the low back rounds.
