Learn how to stretch the sides of your neck (trapezius muscles). Please keep in mind that you should not stretch your neck muscles isometrically or ballistically. It’s not even necessary to pull your head down with one hand, but if you do, make sure not to pull too hard. Neck stretches are important in judo, wrestling, shuai jiao, and combat sports in general.
