Adequate flexibility allows an individual to participate in all daily work and recreational activities with fluidity and without pain. Proper flexibility increases the enjoyment of all activities by freeing the rotation of joints and by reducing the limiting factors of joint range of motion. For any movement, the risk for injury is reduced when flexibility is increased. Coupled with effective strength training, flexibility training balances the functions of antagonist muscle groups, improving the function of both groups. Adequate flexibility also optimizes posture, which is the foundation for safe and effective movement and is aesthetically pleasing.
