The trapezius muscle covers a large area of the back, neck and shoulders. Its main function is to move the scapula, or shoulder blade, and help support your arms. If you spend a lot of time sitting at a desk or behind the wheel of a car, the trapezius muscle can shorten and tighten, which affects mobility in your neck. Stretching this large muscle keeps it loose and pliable, relieves tension and preserves or restores neck and shoulder health.
Stand with your feet hip-width apart or sit in a firm, stable chair. Interlock your fingers behind your head and open your elbows to the side. Gently press your head forward, drawing your chin toward your chest. Avoid rounding your shoulders forward, as this reduces the effectiveness of the stretch.
Stand inside a door frame with your right shoulder adjacent to the frame. Position your feet shoulder-width apart with your toes pointing forward. Extend your left arm across your body toward the right shoulder. Pointing your right thumb down, grab hold of the door frame at shoulder level. Rotate your trunk slightly to the left until you feel a stretch behind your left shoulder. Repeat the stretch with your right arm extended toward your left shoulder.
Stand facing the left side of a door frame, positioning your feet arms-length away from the frame. Lower yourself into a squat position. With your right hand, grab the inside of the door frame at shoulder level. Keeping your right arm straight and your feet firmly planted, lower your hips toward the floor and draw them away from the door frame. You'll feel tension along the back of your right shoulder. Repeat the exercise with your left hand on the door frame to stretch your left trap.
Stand upright with your feet shoulder-width apart. Bring your left arm diagonally across the front of your body, drawing your left hand toward your right hip. Grab hold of your left elbow with your right hand and gently draw the elbow down and toward the right side of your body. Repeat on the other side, pulling your right elbow down and toward the left side of your body.
