What is Half Spinal Twist?
Twisting poses vary across lineages and bodies. A seated version with both legs comfortable is a valid starting point.
Avoid using the arms as levers to wrench the spine.
How do you practice Half Spinal Twist?
Move slowly, keep the breath comfortable, and use the version that feels stable for your body today.
- Sit on a folded blanket with both legs extended or bent comfortably.
- Bend one knee and place the foot on the floor only if the hip and knee allow.
- Sit tall, then rotate the torso gently toward the bent knee without pulling.
- Rest the hands wherever they support an easy posture.
- Return to center slowly and repeat on the other side.
Alignment cues
- Keep the spine comfortably long.
- Let the breath remain natural.
- Reduce the twist if the hips or back feel strained.
Modifications
- Keep both legs extended and cross one ankle over the other.
- Sit on a chair and make a small turn.
- Use a folded blanket under the hips.
Variations
- Simple seated twist.
- Chair-supported twist.
Common mistakes
- Pulling hard with the arm to increase rotation.

- Holding the breath.
Safety notes

- Stop if pain, numbness, or dizziness occurs.
Common questions
How far should I twist?
Only as far as you can turn comfortably while breathing normally. A small rotation is enough.
