Aikido is a non-competitive martial art that can be practiced by almost anyone. Aikido techniques do not rely on physical strength but rather develops relaxed power through the focus of intention and Ki. The result is a creative method of non-destructive conflict resolution.
Aikido is practiced on many levels. The first level is includes the development of stamina, flexibility, and learning how to focus one's intention. The second level is built on the first and stresses self-defense techniques that teach the natural order of movement. In this process the students also become adept at ukemi, the art of rolling, falling and protecting oneself. Aikido provides the opportunity for the development of the entire person. It is a workout of the entire body and mind and results in increased strength, overall physically fitness, flexibility and centeredness.
At the third level students are gradually introduced to the secrets of receiving and harnessing the power of ki, they also develop spatial awareness and learn to judge proper timing and distance. During this training the goal is to establish and maintain an energetic connection to your partner and to lead them off balance. This eliminates the need for more destructive means of resolving situations.
The highest level of aikido is mind over matter. This involves the use of visualization techniques, the power of intention and ki, breath control and meditation. Aikido is truly a spiritual martial art that explores themind - body - spirit connection. This advanced level of training at Shobu Aikido reaches a level not easily found elsewhere. The student learns how to manifest power and effectiveness by the focusing of intention alone. This level depends on and can only be reached through the refinement of technique and the students own deepest feeling. For this reason it alternates between the physical and the spiritual.
In the process of practicing aikido, students inevitably find themselves less stressed and more energetic, better equipped to manage life's many conflicts with calm control. Aikido is great for adults and kids alike because practice encourages respect for self and others, self control, cooperation and responsibility.
Gasshuku or weekend long intensive seminars with William Gleason Sensei are available seasonally.
