Symmetry and Stretching

Another important reason for stretching is to aid in balanced muscle development throughout the body. If one group of muscles is tight and overdeveloped, while another is lengthened and underdeveloped, not only will this look poor aesthetically, but it will contribute to potential future injury. For example, overworking the chest, relative to the back will cause you to have rounded shoulders and look like a gorilla, in addition to causing low back problems.
