Balance is perhaps the most important attribute a fighter can have.
Without it, rooting, power generation, and movement itself is difficult or impossible. Balance may be disrupted in a variety of ways.

Most throws and sweeps require that the opponents balance be broken before these techniques can be executed efficiently.
