Target: Levator scapulae and upper trapezius muscles
For stretching the left side, place both arms behind the back and hold the left wrist with the right hand. Slightly tuck your chin, and then tilt your head to the right. Do not let your left shoulder elevate.
As an option, use your arm to gently pull your head into a lateral tilt. To individualize the stretch for your specific tightness, move your head slightly forward or back to optimize the stretch.
Hold for 30 seconds. Repeat on the other side.
