As most seniors are usually not very physically active, their muscles tend to become taut and inflexible. Flexibility exercises stretch out these muscles and reduce the tension from them, thereby allowing them to move around and feel more confident about themselves. Another advantage of a flexibility workout is that it improves the blood flow to the painful joints of the body, and brings down the inflammation. As a result, the range of motion of the joints affected by arthritis or osteoporosis increases.
