Stretches To Relieve a Tight, Sore Neck: Bridge
Here's a classic yoga pose that allows you to control how much you stretch the back of your neck by how high the hips are lifted. Begin lying flat on your back with your arms along the sides of your body, with your palms facing down. Bend your knees and place your feet flat on the floor. Walk your heels as close as you can to your bum, keeping them hip-width apart.
