This is a lateral twisting pose called Marichyasana III. Dedicated to the sage Marichi.
A great pose to massage and tone the abdominal organs and bring life back into the spine.
Start first with Utthita Marichyasana III. This version is done standing which helps to extend the spine. It is good for those who suffer from low back pain or strain as it helps to release the lower back.
Props: chair, mat, foam blocks, wall
Start in Tadasana (mountain pose) with right hip just touching the wall or just slightly away from the wall.
Press down into the left foot and firm the left knee and quadriceps. Press down into the right foot.
Start to twist from the base of the spine, bringing the right hand behind and the left hand to the outside of the right knee.
Raise the left arm up getting maximum length from the hip to the hand, while keeping the left hip and thighbone pressing down.
Exhale and rotate the trunk to the right.
Forearm points up and open palm.
Press the arm to the knee and knee into the arm. Keep spine lifting up and chest open.
The left side of chest moves toward the right thigh
This is stage I, repeat to other side.
Exhale again and bring right arm around the back to catch the left hand.
Also, watch your straight leg does not tilt. Mine is tilting a little in these last two photos.
