Strength for the Chin

#  1 Keeping your chin slightly lifted, mouth closed, and your back teeth together firmly, press the tip of your tongue against the gum line of your lower teeth, gradually increasing the pressure to the count of 10, hold for 6, and slowly release - at the same time, use 2 fingers at the hollow of your throat (formed by the two upper nodules of the larynx) as resistance - gently pressing in.  Repeat 5 times.

here it is with a bit more detail ... Step 1 Lift chin slightly upward.  With flat point of index and middle fingers press against indentation (hollow)  located at the curve from chin to neck. You will discover the precise location through practice. Finger pressure is the resistance against the working muscles. Step 2 Press your back teeth firmly together  and while maintaining this position.  You will feel the muscles pushing against your finger. Step 3 Press the tip of your tongue against the inside of lower front teeth (gum line) increasing pressure with the tip of tongue in 10 or counts.  For each increase of pressure you will sense the resistance against your fingers. Hold end pressure for 6 seconds. Step 4 Release muscle over 10 counts. Remove finger resistance.  Repeat 5 times.

2 Place your thumb behind the bone just under your chin, press tongue against your lower gums and pretend to touch your tongue to your thumb. Hold 6 seconds.  Repeat 5 times.
#  3 Looking straight ahead place the index finger and thumb on your neck and gently pull the skin down as you lift your head - repeat 10 times. * also at THROAT
#  4 Tighten your chin muscle as firm as you can by pushing your lower lip up and out as though pouting. Squeeze as hard as you can so chin turns white and dimpled. Hold 6 seconds.  Repeat 5 times.
#  5 Begin looking straight ahead with your chin level. Turn your head to the right so that it is even with your right shoulder and then push your head backwards. Hold 6-8 seconds. Return head to forward position with chin level. Turn your head to the left, even with your left shoulder. Push your head back and hold 6 seconds - repeat 6 times.
#  6 Jut out your lower lip as far as possible, place your fingers on your collarbone and point your chin as high as possible and then pull the corners of your mouth down. Hold 6 seconds and repeat 5 times.
#  7 Sit or stand upright and tilt your head to the ceiling while keeping your lips together but not forcing them closed. Start a chewing movement - you will feel the muscles working. Repeat the chewing movement 20 times. This is a good exercise to help rid you of a double chin.  *also at THROAT

Notes

Facial exercises should be done once a day, and this regimen can be continued for your entire life;  after completing a month of daily exercises, for maintenance, you could scale down to three times a week.  Results are visible in approximately one week.
