What is term Extension, in asana movement?
In yoga, extension refers to a movement that involves increasing the angle between two body parts, usually bringing them farther apart. This movement is commonly used to describe the movement of the spine, where extension involves arching the spine backward and lifting the head and chest up. For example, in cobra pose (Bhujangasana), the spine is extended as the chest lifts and the head tilts back. Other examples of extension in yoga include upward facing dog pose (Urdhva Mukha Svanasana), where the spine is extended as the chest lifts and the arms straighten, and bridge pose (Setu Bandha Sarvangasana), where the spine is extended as the hips lift and the chest opens. Extension can help to strengthen and lengthen the muscles in the back, shoulders, and chest, improve posture and spinal mobility, and energize the body and mind. However, excessive or incorrect extension can also lead to compression and strain in the lower back and neck, so it is important to maintain proper alignment and listen to your body’s needs during practice.
