Skeletal System and Yoga Asanas
The human skeleton supports the softer parts of the body such as muscles, which are attached to it and the organs, which it protects. The skeleton, its joints and muscles are exercised through asanas that leads to the proper development of the bones and strengthens them with the passage of time. Disorders in the body such as osteoporosis, Scoliosis, spinal pain and Arthritis are all improved in measurable degrees through the practice of yoga.

The gentle stretching of the muscles and joints releases muscle tension, thus increasing flexibility. The result is to reduce stiffness, which will prevent arthritis or improve it if the person already suffers from the condition. Maintaining many of the asanas encourages strength and endurance. Long term benefits of asanas include reduced pain and improved posture.

Yoga asanas stretch and strengthen these areas and encourage deep full breathing. Yoga for the respiratory system is a vital means of reducing the symptoms that induce respiratory problems.
