DAILY YOGA ยท Kurmasana
Tortoise Pose
Kurmasana โ Tortoise Pose โ is a deep seated forward fold where the arms slide under the knees and out to the sides while the chest lowers toward the floor, drawing inward like a tortoise into its shell. It demands very open hips and hamstrings and cultivates deep introspection.
Name meaning: From kลซrma meaning "tortoise", and ฤsana โ the "tortoise posture". The arms tucked under the legs and the withdrawn head recall a tortoise pulling into its shell; dedicated to Kurma, Vishnu's tortoise avatar.
Classification: Asana โ a deep seated forward bend and inward-drawing pose.
Tradition & origin: A partly-classical case: the upside-down Uttana Kurmasana is genuinely ancient (described in the c.7th-century Ahirbudhnya Samhita and drawn in the 19th-century Jogapradipika and Sritattvanidhi), but this modern seated forward-bend Kurmasana is 20th-century (Iyengar's Light on Yoga). So the name and a related shape are old; this deep fold is modern.

What you may feel

Variations to grow into
Keep the knees bent and the legs less straight, folding only as far as the back stays long.
Supta Kurmasana (Sleeping Tortoise): the feet cross behind the head and the hands clasp behind the back โ for exceptionally open bodies only, with great neck care.
Using props
- ๐งฑA cushion under the sitting bones to tilt the pelvis.
- ๐งฑKeep the knees bent to protect the back while opening.
Warm-up & counterpose
- Seated and wide-angle forward folds, and hip openers, to prepare.

How: Fold over straight legs with a long spine and a strap.
Why: Opens the inner thighs and hamstrings the pose needs.

Who it suits โ and who should modify
- โAdvanced practitioners with very open hips, hamstrings and back.
- โThose wanting a deep, quieting forward fold and an inward focus.
- โPeople who have opened the hips and hamstrings over months (build slowly).
- !Lower-back or disc injury โ keep the knees bent and fold only partway, or skip.
- !Hamstring injury โ sit on a cushion and ease off.
- !Never round and force the arms under the legs; the shape opens over months.
