Head:     Head roll
 

Begin in basic stance: 
Your feet are positioned directly under your hip bones, parallel to each other, and your weight is centered and distributed evenly over both soles. Your knees are slightly bent (soft), and your pelvis is tucked slightly under (pubic bone toward the navel) in the neutral position. Your ribcage is pulled up out of  your waist; your shoulder blades are pulled together and slightly down the spine. Your neck is long, in extension of your spine.

Head roll:
Allow your chin to drop to your chest, then roll your head to the right side (right ear to the right shoulder). Tilt your head slightly back (to avoid compressing your cervical discs, extend your head only so far back that you can still fit your fist between the base of your skull and your upper back), and roll your head to the left side (left ear to the left shoulder). Then allow your chin to drop to your chest again. Do this movement slowly - not everyone is built for whipping her head around, and it is easy but potentially dangerous to drop your head  too far to the back!
