Seal

Seal Exercise Description

Seal (press-up stretch) is a bodyweight spinal extension drill performed in prone. It emphasizes controlled thoracic and lumbar extension while keeping the hips and legs grounded. Primary workers are the spinal extensors (erector spinae), with assistance from the scapular stabilizers (lower trapezius and rhomboids) and elbow extensors to support the press-up. The movement opens the anterior trunk and chest while reinforcing shoulder depression and a long, neutral cervical position. Used thoughtfully, it builds awareness of distributing extension through the whole spine rather than hinging only at the low back.

How To Do The Seal Exercise

‘- Lie prone with legs straight, tops of feet on the floor. Place hands under shoulders, elbows close to your ribs, fingers spread.
– Set shoulders by drawing the shoulder blades down and slightly together; keep your neck long and jaw relaxed.
– Inhale to prepare. As you exhale, press through your palms to lift the chest, sliding the sternum forward and up into spinal extension.
– Straighten the elbows only as far as comfortable without shrugging; keep hips and thighs heavy on the mat.
– Distribute the arc through mid- and upper back; avoid “crunching” the lumbar region. Keep ribs gently anchored and abdomen long.
– Keep gaze slightly forward (not up) to maintain a neutral cervical position.
– Breathe steadily while holding the top position briefly, then lower with control, leading with the chest and keeping shoulders away from ears.
– If straight-arm press-up is uncomfortable, perform a forearm-supported version (Sphinx) and work within a comfortable, pain-free range.

Seal Tips

‘- Lie prone with legs straight, tops of feet on the floor, and hands placed under your shoulders with elbows close to your ribs and fingers spread.
– Before pressing up, draw your shoulder blades down and slightly together to set the shoulders.
– Keep your neck long and jaw relaxed as you move into the press-up.
– Inhale to prepare, then exhale as you press through your palms to lift the chest, sliding the sternum forward and up.
– Straighten your elbows only as far as is comfortable without shrugging, keeping hips and thighs heavy on the mat.
– Focus on spreading the extension through your mid- and upper back rather than hinging only at the low back.
– Keep the ribs gently anchored and the abdomen long to avoid “crunching” the lumbar region.
– Maintain a slightly forward gaze (not up) to keep a neutral cervical position.
– Breathe steadily while holding the top position, then lower with control, leading with the chest and keeping shoulders away from the ears.
– If a straight-arm press-up is uncomfortable, switch to a forearm-supported Sphinx position and work only in a comfortable, pain-free range.

Seal Beginner Introduction

Seal (press-up stretch) is a floor-based backbend that uses bodyweight to create a gentle arch through the spine while the lower body remains anchored. The movement highlights a smooth lift through the mid and upper back, rather than hinging sharply at one spot. As the front of the torso and chest lengthen, the backside of the body works to support the lift, with strong involvement from the back muscles, upper back, and arms.

This pattern emphasizes a relaxed, lowered shoulder position and a long, easy line through the neck, so the head follows the spine instead of jutting forward. When practiced with attention to even motion, it encourages a sense of space across the front of the body and a broad, active upper back. The exercise is often chosen to build awareness of how the whole spine can share extension, which can be especially helpful for people who tend to collapse into the low back during backbending movements.
