Conditioning and Stress Release by Yoga Zone DVD. Some people take up yoga to build strength and flexibility, others are primarily looking to reduce stress and tension. This 55-minute program, while purporting to address both groups, is actually much more appropriate for the latter. Yoga Zone founder Alan Finger does an excellent job not merely emphasizing the importance of the breath -- the single most vital element of any yoga practice -- but also explaining yoga breathing techniques, followed by a series of easy stretches (for the neck, shoulders, arms, and such) and a variety of standing, sitting, and lying poses beneficial to yogis of all levels. The pace is gentle, the sequence of poses logical, the instruction clear and constant. Beginners will be challenged but not intimidated, while more advanced types might find it a welcome alternative to sweaty, aerobic yoga workouts.
