A temporary double chin may not be very sexy, but the alternative of forward head posture is even worse. Perform the chin tuck to help combat neck pain and improve posture.
In an upright position, with your forehead in line with your chin, drive your head backward and hold for 5 seconds. Repeat 10x. The center of your ear should be in line with the tip of your shoulders. If done correctly, you may feel a stretch in the muscles at the base of your skull. Keep your chin and forehead inline the whole time. This one can be done daily.
