Aikido is a Japanese martial art that is an alternative to judo. It is a modern martial art developed in the early 20th century by Morihei Ueshiba, and it focuses on using the opponent's energy against them rather than relying on physical strength. AIKIDO is characterized by circular movements, joint locks, and throws, and it is often used for self-defense. It is also known for its spiritual and philosophical aspects, which emphasize harmony and peace.
