Yoga Asana will challenge the muscles, and joints to access their full potential. When that potential is realized, blood, and nerve impulses can flow freely. You can use different yoga accessories to do so. Each Asana challenges a different network of cells in muscles, tendons, ligaments, and organs. One by one they work systematically into every part of the body.
To master a specific Asana means to release a specific pattern of neuromuscular relationships from all tension. It also means to supply certain muscles, glands, and organs with oxygen, glucose, minerals, and energy through the blood flow.
