At the start of each exercise, it is noted which exercises can be done in bed, wheelchair or pool. Each exercise tells how the exercise will help, as well as any special notes or variations. I think the breath is one of the most important factors in yoga. It is vital to know how to breathe correctly, in order to benefit fully from the asanas. Breathing also affects daily life, and the utilization of correct breath can greatly reduce stress.
Chapter Four gives good instruction on full breathing, along with variations of postures to utilize.
Chapter Five begins the practice with some chair exercises. It starts with simple exercises to stretch and loosen the upper back, neck, shoulders and arms. It then works down the back and introduces some twists and forward bends. Standing postures are addressed in Chapter Six. All of the postures utilize a chair for support if needed.
