Stand up straight and place the middle of a resistance band around the back of your head.
Hold the two ends in each hand in front of you.
Tuck your head back, making a gentle double chin.
You should feel the crown of your head push back into the band.
Ensuring there is always some tension in the band, keeping your head still shake the band forwards and backwards.
The aim of this exercise is to keep your head in the same position while the resistance of the band tries to pull it forwards.
