How to do Little Thunderbolt Pose

Read all of it before starting, and read the cautions further down before starting at all.

  1. Kneel with the knees hip-width apart, shins padded, and hold both heels as in Camel.

  2. Press the hips forward and lift the chest into a strong arch with the thighs vertical.

  3. Keeping the grip on the heels, lower the crown of the head slowly towards the floor behind you.

  4. Let the thighs work eccentrically to control the descent — never drop.

  5. Rest the crown lightly on the mat, hold briefly, then draw the hips forward and pull yourself back up.

Hold: 5–10 seconds. Keep the breath moving throughout — if you are holding it, the pose is too much for today.

What Little Thunderbolt 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.

  • Loads the quadriceps eccentrically through a long descent and then concentrically to return.
  • Takes the spine into deep extension with the pelvis anchored over the knees.
  • Builds the specific strength needed to enter and exit a deep backbend under control.

Little Thunderbolt Pose is one of 43 backbends in this library and one of 61 poses rated advanced. Poses that extend the spine and open the front of the body — chest, hip flexors and abdomen.

Who should skip Little Thunderbolt Pose, or change it

  • Any neck injury — the crown of the head bears weight, so leave this pose out.
  • Disc injury, spondylolisthesis or spinal fusion.
  • Knee injury: the kneecaps carry the load and the knee joint is fully flexed.
  • High blood pressure or glaucoma with the head below the heart and inverted.
  • Shoulder injury that limits reaching back to the heels.

General information only — not medical advice. Some asanas are unsuitable during pregnancy, injury or specific conditions. Learn from a qualified teacher and stop if anything hurts. If you are pregnant, recovering from surgery or managing any health condition, ask your doctor before starting a practice, and learn the pose itself from a qualified teacher who can see you move.

Common mistakes in Little Thunderbolt Pose

What tends to go wrong, and the specific correction — not "engage your core".

MistakeDropping the last stretch of the way and landing on the head.

FixStop practising the full descent until you can hold the halfway point for three breaths.

MistakeThe hips sliding back over the heels, which dumps the arch into the lumbar spine.

FixKeep driving the pubic bone forward so the thighs stay vertical the entire way down and up.

What a practice like this costs in energy

Questions

How do you do Little Thunderbolt Pose?

Kneel with the knees hip-width apart, shins padded, and hold both heels as in Camel. Press the hips forward and lift the chest into a strong arch with the thighs vertical. Keeping the grip on the heels, lower the crown of the head slowly towards the floor behind you. Let the thighs work eccentrically to control the descent — never drop. Rest the crown lightly on the mat, hold briefly, then draw the hips forward and pull yourself back up. Hold for 5–10 seconds.

What does Little Thunderbolt Pose work?

Primarily the quadriceps, hip flexors, spinal erectors, with the glutes, chest, shoulders assisting or lengthening. In mechanical terms: loads the quadriceps eccentrically through a long descent and then concentrically to return.

Who should not do Little Thunderbolt Pose?

Any neck injury — the crown of the head bears weight, so leave this pose out. Disc injury, spondylolisthesis or spinal fusion. Knee injury: the kneecaps carry the load and the knee joint is fully flexed. High blood pressure or glaucoma with the head below the heart and inverted. Shoulder injury that limits reaching back to the heels. This is general information, not medical advice — if any of these apply to you, ask your doctor and learn the pose with a qualified teacher rather than from a page.

Is Little Thunderbolt Pose suitable for beginners?

No. Little Thunderbolt Pose is rated advanced. The shape itself is rarely the problem — arriving at it years too early is. Work through the beginner and intermediate backbends poses on this site and learn this one in person.

How many calories does Little Thunderbolt Pose burn?

The honest answer is that nobody has measured a single asana. The 2024 Adult Compendium of Physical Activities publishes MET values for styles of yoga, not for individual poses. Little Thunderbolt Pose sits closest to Compendium code 02175, yoga, Power, at 4 MET — about 147 kcal for 30 minutes of that kind of practice for a 70 kg adult. Holding one pose for a minute is a rounding error either way.
