Tai chi chuan (literal translation "Supreme Ultimate Fist") is an internal Chinese martial art practiced for both its defense training and its health benefits. It is also typically practiced for a variety of other personal reasons: its hard and soft martial art technique, demonstration competitions, and longevity. As a consequence, a multitude of training forms exist, both traditional and modern, which correspond to those aims. Some of tai chi chuan's training forms are especially known for being practiced at what most people categorize as slow movement.

The solo form should take the students through a complete, natural range of motion over their center of gravity. Accurate, repeated practice of the solo routine is said to retrain posture, encourage circulation throughout the students' bodies, maintain flexibility through their joints, and further familiarize students with the martial application sequences implied by the forms.
