Tortoise Pose
Kūrmāsana
A deep seated forward fold where your arms slide beneath your knees, opening the hips and drawing the senses inward.
Tortoise Pose (Kūrmāsana) is an intense seated fold named after the Sanskrit word kūrma, meaning turtle or tortoise. Resembling a turtle withdrawing into its protective shell, this posture embodies pratyahara, the yogic practice of drawing the senses inward. It is a cornerstone posture in the Ashtanga Primary Series and advanced Hatha systems, requiring exceptional mobility in the hamstrings and hips.

Targets
Hamstrings, Hip adductors, Spinal extensors, Gluteal muscles, Shoulder girdle
Good for
deep hamstring flexibility, hip joint mobility, cultivating internal focus
Breath
Inhale to lengthen your spine forward across the floor, and exhale slowly to soften your shoulders and surrender deeper into the fold.
How to do Tortoise Pose
- 1Sit in Dandasana with your legs extended forward, then widen your feet slightly wider than shoulder-width apart and bend your knees.
- 2Lean your torso forward between your thighs, hinging directly from your hip creases rather than rounding your mid-back.
- 3Slide your arms under your bent knees, threading them out toward the sides with your palms facing down toward the floor.
- 4Walk or slide your heels forward along the mat to gradually straighten your legs as far as your mobility safely allows.
- 5Press your thighs gently down against the backs of your upper arms to anchor your pelvis and extend the spine forward.
- 6Lower your chest, chin, or forehead toward the mat while reaching your inner heels actively away from your pelvis.
- 7Hold the posture for five to eight deep, steady breaths, keeping your jaw relaxed and your mind focused inward.
- 8To exit, bend your knees deeply to relieve pressure, carefully unthread your arms from beneath your legs, and roll up slowly to sit.
Benefits
- Lengthens the hamstrings and calves along the entire posterior chain
- Deepens external rotation and abduction mobility in the hip joints
- Stretches the deep supportive muscles along the lumbar and thoracic spine
- Expands the shoulder girdle through horizontal abduction of the arms
- Encourages down-regulation of the nervous system through sensory withdrawal
- Tones the abdominal organs through gentle, supported compression
Common mistakes and cues
Forcing legs straight
Over-straightening the knees before the pelvis can tilt forward places excessive strain on the proximal hamstring tendons and lower back.
Aggressive upper back rounding
Collapsing through the thoracic spine prevents the front body from lengthening and can cause neck strain.
Internally rotating shoulders awkwardly
Forcing the arms under the knees without adequate shoulder mobility pinches the rotator cuff and anterior shoulder capsule.
Holding the breath
Restricting respiration triggers a stress response that causes the hamstrings and hips to contract defensively.
Letting feet splay passively
Allowing the feet to roll outward destabilizes the hip joints and misaligns the knee tracking.
Modifications and props
Bent knees
Keep your knees generously bent with your heels drawn in closer to reduce tension on the hamstrings and lumbar spine.
Blocks under heels
Elevate your heels on yoga blocks to create extra clearance under the knees for threading your arms.
Bolster under chest
Rest your sternum and forehead on a bolster placed between your legs to support your torso and prevent overstretching.
Half Tortoise prep
Thread only your forearms under your knees while keeping your torso semi-upright to gradually build hip flexibility.
Cautions
Hamstring injuries
Avoid this posture during acute hamstring tears or tendinopathy, as the seated leverage places high tension at the sit bones.
Lumbar disc herniation
The extreme spinal flexion involved can increase intervertebral pressure and aggravate disc pathologies.
Shoulder impingement
Bearing leg weight over compromised shoulder joints can worsen rotator cuff inflammation or labral issues.
Pregnancy
The deep abdominal compression makes this posture contraindicated throughout all stages of pregnancy.
If you are working with an injury, pregnancy or a medical condition, check with a qualified professional before practising this pose.
