Adho Mukha Svanasana (downward dog) is likely an asana (pose) that all yoga classes incorporate. In examining this asana can you achieve regulation in your nervous system when doing this pose and create mobility, stability integration and consolidation? The answer is yes if completed correctly. For this you will need to be instructed in how to take the pose properly.

There should be symmetry between the left and right sides of the body and an even distribution of weight on the palms and the feet.

1. Start on all fours with your hips above your knees and shoulders above your wrists and hands slightly forward of your shoulders. Adjust the distance such that the weight is distributed evenly between the legs and arms. Think of straight line down the middle of your mat and from the top of your head to your heals with equal spreading from the centre to each outer edge evenly.
2. Every movement is done with a full exhalation and followed by inhalation and held for time to allow for the feedback to complete.
3. Press your hands down completely, extend your fingers, straighten you elbows completely and from the action of your shoulder blades by pressing off your wrists turn your inner upper arm outwards and shoulder blades moving down your back and spreading each one to the right and left. Create a spiral action in your arms by rolling your upper arms away from you and your forearms spiralling inwards.
4. Keeping your arms firmly in this position, head up, lift your hips up with bent knees. Lengthen your spine and by lifting the bones of your upper legs inward towards your pelvis work to straighten your legs pressing your thigh bones back. Do not push merely your knees back but create mobility and stability in your hips, alignment in your legs from your feet through your knees while maintaining the same stability from your hips to hands.
5. Slide your shoulder blades down along the spine, collar bones spread with the base of the neck relaxed.
6. Abdomen should move inward by plugging your tailbone in, lifting your pubic bone up slightly and moving your navel back so the entire organic body sits back and rests in place.
7. To activate your parasympathetic nervous system, circulatory system and to receive calm and balance, you must be able to breathe, sustain the pose and stay present until lightness comes. Lightness comes thought balanced resistance, mobility, stability, and mindful connection to these areas. It is hard to perform a posture correctly without simultaneously concentrating on the form and breath.
8. There are at least 22 variations of this pose using props to create the shape of the pose through adaptation to teach it properly and to allow everyone to be able to access the benefits of the fully aligned pose.
