Bent Arm Chest Stretch
- Beginner
- Isolation
- Timed hold
- Chest
- Shoulders
This unilateral stretch targets the pectoralis major and anterior deltoids to improve shoulder mobility and counteract rounded-shoulder posture. The 90-degree arm bend focuses the tension directly on the chest fibers rather than the biceps or distal tendons.

Setup
- Stand perpendicular to a wall or doorframe with your feet in a staggered stance.
- Bend your target arm to 90 degrees and place the entire forearm and palm flat against the wall.
- Position your elbow so it is level with or slightly above your shoulder height.
How to do it
- Exhale as you slowly rotate your torso away from the wall while keeping the forearm pinned firmly in place.
- Lean your body weight slightly forward into the staggered leg until you feel a deep stretch in the chest and front shoulder.
- Hold the position for 30 seconds, maintaining deep, rhythmic diaphragmatic breathing.
- Slowly release the tension by rotating back toward the wall and repeat on the opposite side.
Form checklist
- Keep your shoulder blade pulled back and down, avoiding the tendency to shrug.
- Ensure the elbow stays at a 90-degree angle to maximize pectoral tension.
- Maintain a neutral spine and avoid arching your lower back during the rotation.
- Rotate your entire torso as one unit rather than just twisting your neck.
Pro tips
- To target the lower pectoral fibers, slide your elbow slightly higher on the wall; to target the upper fibers, move it slightly lower.
- Focus on the mind-muscle connection by imagining your chest muscle lengthening with every exhale.
Make it harder
- Incorporate PNF stretching by pressing your forearm into the wall with 20% effort for 5 seconds, then relaxing and moving deeper into the stretch.
- Perform the stretch with a slight forward lean of the entire torso to increase the leverage on the shoulder joint.
