Traditional martial art teaching includes a low and wide stance known as Ma Bu, or Horse Stance. This stance develops leg strength, or rootedness. I the Earth Dragon Canon method, we abandon wide and deep stances for proper alignment and function. This does not mean, however, that we can abandon leg strength.
We need a posture that can engage our leg muscles in a functional manner without dedicating hours to just standing around. My version of the Horse Posture is similar to the Bear Posture, but against a wall and standing up.
