AS can make you lean forward. That can cause your neck to get tight and give you headaches. This move can strengthen your neck to keep you upright and relieve tightness.
Lie on your back. Without lifting your head off the floor, tuck your chin in slightly toward your chest. Hold for 5 to 10 seconds. Repeat 3 to 5 times.
Do this stretch twice a day.
Uncomfortable? Try a small, rolled-up towel under your neck for support.
