"The visible bump is in the back, so everyone attacks the back of the neck. But the muscle pulling the head forward often sits on the front and sides. It is called the SCM, and years of phone/desk posture can keep it locked like a clenched fist. That is why chin tucks feel like homework and posture braces collect dust. They train the position. They do not release the pull. Hizoo is built to knead both sides of that muscle with heat while you lie down for 10 minutes."
