Setup Instructions

Kneel sideways on the carriage with one hand on the footbar and the other arm reaching overhead.

Execution Instructions

  1. Press the carriage away and back with the hand while keeping the torso tall and the hips stacked.
  2. Exhale to press out, inhale to return with control; keep the shoulders level and the working arm long, resisting the urge to hinge at the waist or drop the hip.

Teaching Cues

Alignment

"Stack the hips and keep the spine tall — no leaning."

Control

"Press from the shoulder while the torso stays still."

Breath

"Exhale as the working arm presses the carriage away, inhale as it returns overhead."

Modifications & Progressions

Hand on Hip (Regression)

Rest the top hand on the hip and press through a shorter range until the torso stays tall.

Overhead Two-Breath Press (Progression)

Hold the press at the end of the range for two breaths with the top arm reaching overhead before returning.

Padded Knee Press (Injury Modification)

For knee issues, pad under the kneeling knee, keep the hips stacked over it and press only a short range.
