The Ai Chi modality was developed in 1993 by Jun Konno, and is a form of aquatic exercise i.e. water exercise applied for recreation, relaxation, fitness, flexibility, strength, and physical rehabilitation i.e. therapy.
Ai Chi is typically performed standing, in shoulder-depth water, with slow, continuous, and broad movements of the arms, legs, and upper part of the body.
The practice is also combined with mental focus i.e. mindfulness on the flowing movements, on proper body alignment, and coordinated breathing. Ai Chi can be practiced in group classes or in one-on-one therapy sessions.
