The doorway pec stretch is performed by standing in a doorway and placing your forearms or hands on the doorframe with your elbows positioned at about shoulder height. Once your arms are supported on the frame, take a small step forward and gently lean your body through the doorway until you feel a comfortable stretch across the front of your chest and the front of your shoulders. Keep your neck relaxed and avoid arching your lower back as you lean forward. Hold the position for twenty to thirty seconds while breathing normally, then step back to release the stretch. This can be repeated two or three times and practiced once or twice daily.
The benefit of the doorway pec stretch is that it lengthens the pectoral muscles, which are often tight in people with rounded shoulders or prolonged sitting or repetitive front-oriented tasks. By opening the chest and reducing anterior shoulder tightness, the stretch helps improve posture, decrease tension in the shoulders and upper back, relieve neck strain, and support healthier shoulder mechanics. It can also enhance overhead arm movement and improve breathing comfort by reducing restriction across the front of the rib cage.
