Yoga for a Strong and Healthy Back presents the fundamentals of posturing and breathing in this approachable 40-minute workout that includes two 20-minute sessions focusing on spinal rotation and muscular strength. The back is central to supporting all movements; conventional workouts often do not include exercises that strengthen the lower back. Yoga Zone gives excellent instruction here, and participants are taught poses that utilize both the lower and upper back. The warrior pose and forward bends are just a few of the postures performed here that can improve spinal flexibility and help to avoid future back injuries. Beginners should find the first set easy to follow (the postures within this section are modified versions of what is yet to come). The second set incorporates some back bends and deeper poses that require greater agility and strength. Despite the increased difficulty here, participants of all levels can improve their flexibility without being overwhelmed by impossible poses.
