BJJ is a democratic martial art. Any person, with the appropriate training, is capable of executing its moves and using self-defense in their favor, no matter their size or power.
The art can be particularly useful to women trying to ward off attackers — not only for the moves that can incapacitate these aggressors, but also for the confidence that the knowledge can provide.
To make this less theoretical, Professor André Ushirobira recruited his white-belt student Sara to demonstrate some self-defense moves.
