Assisted Seated Pectoralis Major Stretch With Stability Ball
Assisted Seated Pectoralis Major Stretch With Stability Ball Exercise Description
The Assisted Seated Pectoralis Major Stretch with a stability ball is a partner-assisted chest stretch performed in a supported, upright sitting position. It primarily targets the pectoralis major while also creating a gentle stretch across the anterior shoulder (including the anterior deltoid). Sitting on the ball encourages neutral spine and light thoracic extension as the partner guides the arms into controlled horizontal abduction. The focus is a mild, even stretch across the chest—not pressure in the front of the shoulder or neck. This variation suits individuals who can sit stably on a ball and communicate continuously with a partner to keep the shoulder joint within a comfortable, safe range.

How To Do The Assisted Seated Pectoralis Major Stretch With Stability Ball Exercise
‘- Select a ball height that allows feet flat on the floor and hips/knees near 90 degrees; take a wide, stable stance.
– Sit tall on the ball with a neutral spine; ribs stacked over pelvis, chin slightly tucked, and light abdominal brace.
– Gently set the shoulders: slight scapular retraction and depression (down and back) without flaring the ribs.
– Raise arms out to the sides at shoulder height with a comfortable elbow bend; palms forward or thumbs up to promote slight external rotation.
– Partner stands behind, places hands on your outer elbows/forearms, and applies slow, symmetrical pressure guiding the elbows slightly backward while you “lead with the sternum.”
– Keep neck relaxed; avoid shrugging, anterior humeral glide (shoulders drifting forward), or excessive low-back arching.
– Stop at the first point of a comfortable chest stretch; breathe steadily and maintain even alignment.
– Partner releases pressure gradually; you return the arms to the starting position under control.
– If you feel pinching at the front of the shoulder, lower arm height or increase elbow bend and try again; never force the range.
Assisted Seated Pectoralis Major Stretch With Stability Ball Tips
‘- Choose a ball height that lets your feet stay flat with hips and knees near 90°, and take a wide, stable stance.
– Sit tall on the ball with a neutral spine, keeping ribs stacked over your pelvis and your chin slightly tucked.
– Lightly brace your abdominals to help maintain the neutral spine as you stretch.
– Set your shoulders by gently drawing the shoulder blades down and back without letting the ribs flare.
– Raise your arms to shoulder height with a comfortable elbow bend and palms forward or thumbs up.
– Ask your partner to apply slow, symmetrical pressure at your outer elbows/forearms, guiding them slightly backward.
– “Lead with the sternum” as the partner moves your arms to encourage a mild, even stretch across the chest.
– Keep your neck relaxed and avoid shrugging, shoulders drifting forward, or excessive arching in your low back.
– Stop at the first point of a comfortable chest stretch, breathing steadily and keeping your alignment.
– If you feel pinching at the front of the shoulder, lower your arm height or increase elbow bend and try again, without forcing the range.
Assisted Seated Pectoralis Major Stretch With Stability Ball Beginner Introduction
The Assisted Seated Pectoralis Major Stretch with a stability ball is a partner-based chest stretch done in an upright seated position on the ball. It highlights a gentle lengthening through the chest and the front of the shoulders, including the front of the upper arm area, while the ball offers a supported base. As the arms move outward and slightly back, the upper back naturally lifts a little, encouraging a tall posture without straining the neck.
This stretch centers on comfort, balance, and subtle control rather than intensity. The partner stands behind and lightly guides the arms to open, creating an easy, even pull across the chest instead of pressure at the front of the shoulder or along the neck. The person stretching maintains steady breathing and a calm, relaxed neck while the chest broadens. Continuous communication between both people helps the movement stay within a safe, pleasant range, with the arms returning smoothly to the starting position once the stretch is complete.
