Yoga Pose- Dancer’s Pose (Natarajasana)

0 Yoga Pose  Dancers Pose (Natarajasana)http://www.doyogawithme.com

http://YogaYak.com will be reposting this most excellent series of classes.

Yoga Pose- Dancer’s Pose (Natarajasana)

Nata is a dancer; raja is a lord or king. Fiji takes you through a few versions dancer’s pose that are progressively more difficult, finishing with full Natarajasana. This pose requires a significant amount of flexibility in the hip flexors and spine, as well as an unwavering sense of balance.

From Yogayak.com:

Dedicated to Lord Shiva (Lord of the Dances in Hindu tradition), the Dancer is a graceful and elegant balancing pose that stretches the shoulders back and legs, opens the chest and requires flexibility and strength. It can be modified to suit different skill levels. In it fullest expression Natrajasana is a celebration of the strength and movement of the body.

Benefits: reduces menstrual discomfort and PMS symptoms, opens the chest and heart, improves lung capacity and quality of breath, improves posture, tones the spine; strengthens arms, abdominals, hip flexors, legs (inner thighs and quadriceps), stretches and tones arches of the feet; rejuvenating and uplifting, increases focus, reduces effects of stress, anxiety and mild depression

Drishti: Forward, down the length of the arm and past the fingertips
Technique: begin in Tadasana (Mountain), reach your right arm behind you to grasp your right foot (or ankle); inhale and lift your left arm above your head, keeping the arm hugged close to the ear, exhale and press your right leg against your right hand, engaging the thigh muscles to send the leg back; inhale and lengthen through your spine, finding comfortable balance in the pose; exhale and bend forward at the hips, extend your left arm forward, your torso bending toward the floor, gaze down the length of your arm, past the tips of your fingers, remain here for a few breaths, slowly bring your torso upright, release the leg to the floor, release the arm, repeat on the other side

Modifications: if you are not flexible through your spine, shoulders or hips, do not press your leg back, simply hold your leg bent and close to your body, raise the opposite arm above your head and lean forward slightly, as is comfortable for you; alternatively if you are slightly more flexible you may use a strap to wrap around the back foot; if you are very flexible, deepen the arc in your spine and bring your foot closer to your head, do this only if you can maintain comfortable balance in this posture and progress slowly, listening to your body at all times

Contraindications: high blood pressure, vertigo, prone to fainting, knee, back or shoulder injury (ensure you modify the pose to be comfortable for you or skip it all together) – there is no pain in yoga

Counterpose: Standing Forward Bend (Uttanasana)

Snoring chin strap

0 Snoring chin strapAll You’ll need Is here now – http://goo.gl/tQkyY

Snoring research proves that a chin supporter (worn throughout sleep time) which helps to keep the bottom jaw in an ” up ” posture increases the three dimensional room in the airway tube which lessens air rate together with soft tissue vibration. Simply by raising the volumetric capacity of the air passage and reducing soft tissue vibrations, snoring can be avoided or substantially decreased. The My Snoring Solution jaw supporter easily retains the lower jaw in an upward/forward position and enhances three-dimensional room in the airway.
