유도 Udo / Jiujitsu

U means “soft” or “flexible.” Do means “way.” Udo translates to "Flexible Way.”

The form is soft and develops proper falling techniques without injury by keeping the body flexible and developing coordination and strength. The practitioner develops self-defense against strikes, grabs, and kicks in both offensive and defensive movements, using the opponent's strength against them. Precise placement of the feet is vital, and strong hand grips are applied over the opponent's entire body. Strikes are in all different directions, using more circles than angles. This training develops flexibility throughout the body, particularly in the spine. Agility and coordination are greatly increased. The practitioner develops the control, coordination, and flexibility, to make the body round. This ability is needed to roll comfortably and avoid injury when rolling like a wheel at a 45-degree angle.

Udo is most effective at close range. For Udo to work one must grab the opponent and throw them to the ground. Hitting the ground is what causes the injury and disables the opponent.
