How to do Thunderbolt Pose
Read all of it before starting, and read the cautions further down before starting at all.
Kneel on a mat with a folded blanket under the shins if the floor is hard.
Bring the knees together and the big toes touching, letting the heels separate slightly.
Sit back onto the heels; if that is far, place a block or bolster between the heels and sit on that.
Stack the shoulders over the hips and rest the hands on the thighs.
Lengthen the spine, keep the front ribs soft, and hold with even breathing.
Hold: 1–5 minutes. 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 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 into a fully shortened position while the knees are deeply bent.
- Holds the ankles and the tops of the feet in plantarflexion against the floor.
- Gives a very stable base that lets the spine hold vertical with little effort.
Thunderbolt Pose is one of 29 seated poses in this library and one of 88 poses rated beginner. Poses taken on the floor, where the pelvis is the base and the spine works above it.
Who should skip Thunderbolt Pose, or change it
- Knee injury, meniscus repair or knee replacement — kneel only with a bolster, or sit on a chair.
- Ankle injury or a bony ankle that will not tolerate pressure: roll a towel under the ankles.
- Varicose veins in the calves, where prolonged deep knee flexion is uncomfortable.
- Foot pain in the toes or arches — turn the toes under only if that is comfortable, or skip.
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 Thunderbolt Pose
What tends to go wrong, and the specific correction — not "engage your core".
MistakeSitting straight down onto the heels when the knees are not ready.
FixPut a block between the feet and build the range over weeks.
MistakeLetting the heels splay wide so the ankles roll.
FixKeep the big toes together and the heels just wide enough for the seat.
How the energy figure on a yoga timetable is reached
- Nobody has measured a single asana in a metabolic cart, so no per-pose figure is published here — not by this site and not by anyone.
- The pose is matched to the nearest style of practice in the 2024 Adult Compendium of Physical Activities. Thunderbolt Pose sits at code 02150, ਯੋਗਾ, ਹਠ, 2.5 MET.
- That MET value is put through the standard ACSM relationship for a stated reference adult of 70 kg.
- The result is the cost of a practice of that kind for as long as you practise — not the cost of holding this one shape.
- Scale it to yourself: the relationship is linear in body mass, so multiply by your own weight in kilograms and divide by 70.
kcal/min = MET × 3.5 × kg ÷ 200
= 2.5 × 3.5 × 70 ÷ 200
= 3.06 kcal per minute

Read it the way you would read a timetable: pick the length of session you actually sit down for, and that is the figure.

Asked before class
How do you do Thunderbolt Pose?
Kneel on a mat with a folded blanket under the shins if the floor is hard. Bring the knees together and the big toes touching, letting the heels separate slightly. Sit back onto the heels; if that is far, place a block or bolster between the heels and sit on that. Stack the shoulders over the hips and rest the hands on the thighs. Lengthen the spine, keep the front ribs soft, and hold with even breathing. Hold for 1–5 minutes.
What does Thunderbolt Pose work?
Primarily the quadriceps, ankles, spinal erectors, with the feet, abdominals, hip flexors assisting or lengthening. In mechanical terms: loads the quadriceps into a fully shortened position while the knees are deeply bent.
Who should not do Thunderbolt Pose?
Knee injury, meniscus repair or knee replacement — kneel only with a bolster, or sit on a chair. Ankle injury or a bony ankle that will not tolerate pressure: roll a towel under the ankles. Varicose veins in the calves, where prolonged deep knee flexion is uncomfortable. Foot pain in the toes or arches — turn the toes under only if that is comfortable, or skip. 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 Thunderbolt Pose suitable for beginners?
Yes. Thunderbolt Pose is a beginner-level pose on this site, which means it is learnable in a first class and has a version that works for most bodies. The cautions above still apply.
How many calories does 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. Thunderbolt Pose sits closest to Compendium code 02150, yoga, Hatha, at 2.5 MET — about 92 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.
