Yoga exercises have become a popular way to improve health, maintain a normal body weight, relieve stress and stretch for a more flexible body. All of these are very helpful for any age, but for older Americans, the benefits are even more important. The stretching becomes more important as baby boomers age, and meditation helps in reducing stress that can be caused by not only caring for elderly parents, but also supporting adult children and helping with grandchildren. However, there are warnings that must be taken seriously before embarking upon a program of yoga moves.
