Stretches the lower back without requiring loose hamstrings
Targets the ligaments along the back of the spine
Stimulates the liver and kidneys and aids digestion (when folding over the straight leg) [1]
Contra-indications:
Can aggravate sciatica. If you have sciatica, elevate the hips by sitting on a cushion until the knees are below the hips, or avoid this pose entirely. Beware of hips rotating backward while seated; we want them to rotate forward.
If you have any lower back disorders that do not allow flexion of the spine, do not allow the spine to round: keep the back as straight as you can or do the reclining version.
Avoid dropping the head down if the neck has suffered whiplash or has reverse curvature.
Beware of any sharp pain in the knees. If you have issues in this area, tighten the top of the thigh (engage the quadriceps), which will close the joint or bring the legs closer together.
If the bent knee complains, place support under that thigh or move that foot away from the groin.
If the hamstrings protest, bend the straight knee and support the thigh with a blanket or block
Getting Into the Half Butterfly Pose:
From a seated position, draw one foot toward you and stretch the other leg straight to the side. Allowing your back to round, fold forward, and down the middle between both legs.
Alternatives & Options:
Folding over the straight leg may stretch the hamstrings more
Reach the opposite hand to the extended foot and lower that shoulder to emphasize the side of the spine
Add a twist to the spine by resting the elbow on the thigh and the head in that hand (or, for more flexible students, placing the arm alongside the straight leg) and the other arm behind the back or over the head. Rotate the chest toward the sky. This deepens the emphasis along the side of the ribs and spine
Place the foot of the bent knee in Virasana (folded backward behind the buttock), but only if the knee doesn’t complain
Coming Out of the Half Butterfly Pose:
Slowly roll up, pushing the floor away with your hands. Before straightening the opposite leg, lean on your hands to release the hips. Then, slowly straighten the leg
Counter poses:
Sitting up or a gentle sitting back bend
Flow into Tabletop (aka Hammock)
Windshield Wipers
Meridians & Organs Affected:
Urinary Bladder;
If there is a lot of sensation in the groin and inner legs, the Liver and Kidneys are stimulated
Joints Affected by Half Butterfly Pose:
The spine, especially the back and side
Knees, knees, although this is not as deep of a stretch for the inner knees as the Dragonfly
Recommended Hold Times:
This can be held for a long time, about five minutes, with the variations added after about three minutes
Similar Yang Asanas:
Janu Sirsasana, but here we aren’t trying to bring the head to the foot; instead, we are bringing the head to the knee. Allow the back-to-round
This pose is excellent for pregnant women because the legs are abducted, providing space for the belly
Paul Grilley calls the variation with the foot in Virasana the Half Frog Pose
