The mud walking step is not the only step used in circle walking.
There are others, like the heel to toe stepping pattern which is called different things in different systems. Some people call is the Lion Step and others " Immortal Man Strolling". I walk my circle as in real life and I DO NOT walk with a mud step so I avoid that one. I use that step as a way to train how to kick someone in the shins very quickly without raising the foot, just shooting it out, Jeet Gerk(arrow kick).
Mouth Boxers have not the testicular nor the spinal fortitude to be known.
Hence they hide rather than be known as adults.
