Full Face
Joker Grin: Try to pull entire face strongly away from nose/center by grinning frantically.
Nose Wrinkle: Try to pull entire face strongly into a wrinkled knot around nose.
(Alternate between the two and try to incorporate as many muscles as possible like neck, throat, scalp, tongue, ears etc when doing them. This is the 'dead lift' for your face and should always be exercise #1. For extra effect, combine with body work out like squats!)

Neck Crunch:
Lie on back. Slowly raise head until chin touching chest. Lower slowly.

Under Chin/Tongue:
-Apply pressure against curve from chin to neck. Close bite firmly. Press tip of tongue against lower front teeth to work muscle.

-Push lower lip up and down using chin muscle.

Cheeks :

-Push cheek out with thumb and bring the cheek back towards teeth against the pressure.
-Form an exaggerated "O" with your mouth by pushing your lips out as far as possible. Then smile is brightly as you can.
-pull bottom lip over top lip smile. Tilt chin slightly upwards until feel pulling on neck.

Eyes :
-partially winking one eye at a time, and holding the wink for a second, and then repeating the movement.
-Place three centre fingers underneath the eye, pull down, and try to close your eyes.

-place index fingers under eyebrows. Push up while closing eye.
