Gravity and aging can take a toll on your face and neck. The muscles of your face and neck are just like any other muscles. If you don’t exercise these muscles, they will become weak and you can lose muscle tissue. Tightening and toning the muscles of the face and neck can help reduce the effects of aging and help you look and feel a little younger. People whose cheeks and jowls are sagging can help reduce the saggy appearance by doing some face and neck exercises. These exercises can be performed any time, while watching television, sitting at your desk at work or just about anywhere. 

Sit in a comfortable chair with your back straight. Drop your shoulders a bit and pull your shoulder blades back so that your spine is straight. Look straight ahead and press your chin forward. Squeeze your lips together and then lower your jaw and push your jaw forward. Hold this position for about 10 seconds and then relax. Repeat this exercise 5 times. This exercise will help strengthen and tone the muscles of your lower jaw and neck. 

While still sitting upright in your chair, tilt your head back. Keep your mouth closed, but not tightly. Move your lower jaw in a chewing motion left to right 10 times and then reverse and move your jaw right to left 10 times. Relax and rest for a few seconds if your jaw gets tired. Do 3 to 5 sets of 20 chewing exercises each day. Stretch  your neck muscles by tilting your head back and look at the ceiling. Thrust your lower jaw forward slightly and cover your upper lip with your lower lip. Hold the stretch for about 5 seconds and then relax. Repeat this stretch 10 times each day. 

Lie on your back on the bed with your head hanging over the edge. Slowly and smoothly raise your head until your spine is straight. Hold the straight position for 10 seconds and then slowly relax and lower your head back to the start position. Repeat this exercise 5 times each day.
