Sub-occipital Stretch
Step 1;
Stand upright, with your shoulders relaxed, and place your index finger on your chin.
Step 2;
Use your finger to push your chin backwards - the sub-occipital muscles are small muscles between the bottom of the skull and the top of the neck which is where you should feel a gentle stretch.
This exercise is easier to do in front of a mirror so you can tell if you have tipped your chin upward or downward as your head should go straight backwards.
