Reclining Thunderbolt Pose
सुप्त वज्रासन
Supta Vajrāsana — an advanced seated pose that works the quadriceps, hip flexors, abdominals.
How to do Reclining Thunderbolt Pose
Read all of it before starting, and read the cautions further down before starting at all.
Begin kneeling in Vajrasana with the shins padded and the seat resting between or on the heels.
Walk the hands back behind the hips and lean onto the forearms one at a time.
Stop here if the thighs or knees are already loaded; this is the working depth for most people.
If the knees stay quiet, lower the back towards the floor and rest the crown or the back of the head down.
Keep the knees as close together as they will stay, hold briefly, then press back up through the forearms.
Hold: 15–30 seconds. 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 Reclining 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.
- Lengthens the quadriceps and hip flexors with the knees already fully bent, which is their longest available range.
- Extends the thoracic spine and opens the front of the chest.
- Loads the abdominal wall eccentrically on the way down and concentrically on the way up.
Reclining Thunderbolt Pose is one of 29 seated poses in this library and one of 61 poses rated advanced. Poses taken on the floor, where the pelvis is the base and the spine works above it.
Who should skip Reclining Thunderbolt Pose, or change it
- Any knee injury or knee replacement — skip entirely.
- Low back or disc injury, since the lumbar spine takes the arch if the thighs do not give.
- Sacroiliac pain.
- Ankle injury, and pregnancy at any stage.

Common mistakes in Reclining Thunderbolt Pose
What tends to go wrong, and the specific correction — not "engage your core".
MistakeLetting the knees drift wide apart to get the back down.
FixKeep the knees together and stop at the forearms; a wide-knee version loads the joint sideways.
MistakeSliding the hips forward off the heels while lowering.
FixKeep the seat anchored — if it lifts, you have gone past your range.

Is Reclining Thunderbolt Pose suitable for beginners?

How many calories does Reclining 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.
