The Tai Chi program consists of a unique combination of 8 single forms, largely derived from the traditional 24-form Yang Style,22 which was modified and simplified for older adults.19 The movements of each form are based on fundamental principles of traditional Tai Chi that emphasize alternate single- and double-leg weight-bearing stances, postural alignment, and coordinated movements that are executed in a gentle, continuous, circular, and flowing manner. Although each single movement within a form traditionally requires a coordinated breathing cycle, natural breathing is encouraged to reduce participants’ attention demands. The 8 individual forms are arranged in a sequence that progresses from easy to more difficult. Each form can be performed and practiced separately or practiced jointly in a set.
