How to do Flapping Fish Pose
Read all of it before starting, and read the cautions further down before starting at all.
Lie face down and turn the head to the right, resting the cheek on the mat.
Bend the left knee out to the side and draw it up towards the left ribs.
Slide a folded blanket or a small pillow under the bent knee so the leg is supported, not hanging.
Interlace the fingers loosely and rest the head on the backs of the hands, or place the arms wherever they are heavy.
Stay for half the hold, then swap the head and the knee to the other side.
Hold: 3–6 minutes each side. Keep the breath moving throughout — if you are holding it, the pose is too much for today.
Muscles worked
Where the effort and the lengthening land. Primary groups do most of the work; secondary groups assist or are stretched.
What Flapping Fish Pose does
Described mechanically — what the movement does to muscle and joint. Not a list of conditions it treats, because a pose does not treat conditions.
- Gives a mild asymmetric position with the whole front of the body resting on the floor.
- Opens the hip of the bent leg outward while a prop takes the weight of the thigh.
- Requires no effort at all once the props are placed, so it holds well for long periods.
Flapping Fish Pose is one of 21 restorative poses in this library and one of 88 poses rated beginner. Supported, low-effort poses held long, where the point is to stop working rather than to work.
Who should skip Flapping Fish Pose, or change it
- Pregnancy after the first trimester — face-down positions are unsuitable; use a side-lying rest.
- Low back discomfort in prone poses, which the bent knee can increase.
- Neck problems from a long turned-head hold: change sides halfway and keep the turn small.
- Knee or hip injury on the bent side.
