Seated Chest Clam

Seated Chest Clam Exercise Description

The Seated Chest Clam is a simple bodyweight chest opener performed while sitting on a stable chair or bench. It targets the pectoralis major and minor and the front of the shoulders, while encouraging scapular retraction and depression for better shoulder positioning. You’ll create the stretch by placing the hands behind you and gently drawing the shoulders back and down as the chest lifts. Keep a neutral spine and relaxed neck so the movement comes from the shoulders, not the lower back. Use a comfortable, pain‑free range and breathe steadily throughout.

– Draw your shoulder blades down and together; let the chest lift forward without flaring the ribs.
– Keep your neck long with a slight chin tuck and eyes forward; avoid craning the head.
– Gently slide the hands down/back to “open” the front of the shoulders and chest; do not shrug. ([us.physitrack.com](https://us.physitrack.com/home-exercise-video/seated-chest-opener%C2%A0dynamic-stretch?utm_source=openai))

– Breathe slowly and ease out of the stretch under control; stop if you feel joint pinching or sharp pain.

Seated Chest Clam Beginner Introduction

The Seated Chest Clam is a gentle, chair-based stretch that uses only bodyweight to create space through the front of the chest and the front of the shoulders. It is done while sitting on a stable chair or bench, making it suitable for small spaces or office settings. By positioning the hands behind the body and easing the shoulders backward and slightly downward, the front of the upper body gradually lengthens, while the shoulder blades glide toward each other for a more supported shoulder position.

Throughout the movement, the back stays in its natural curve and the neck remains relaxed so the action centers around the shoulders rather than the lower back. The stretch is intended to feel mild and comfortable, with no pushing into sharp or pinching sensations. Steady, unforced breathing accompanies the position, which can help release tension across the chest from prolonged sitting or rounded postures. This creates a simple upper‑body opener that emphasizes calm control, shoulder alignment, and awareness of posture.
