Yoga is a gentle way to improve your posture, balance, and coordination. Yoga is a systematic practice of physical exercise, breath control, relaxation, diet control, and positive thinking and meditation aimed at developing harmony in the body, mind, and environment. To convey its spiritual message and guide sessions, yoga often uses the imagery of a tree with roots, a trunk, branches, blossoms, and fruits. Each “branch” of yoga represents a different focus and set of characteristics.
