Seated Spinal Twist

HOW TO DO IT
  1. 01Sit tall with one leg crossed over the other, foot flat on the floor.
  2. 02Lengthen the spine upward first — height before rotation.
  3. 03Rotate towards the top knee, using the arm as a gentle guide only.
  4. 04Keep both sit bones grounded. Hold 45 seconds each side.
COACHING CUES
  1. 01Grow taller before you turn.
  2. 02Rotate from the mid back, not by cranking with the arm.
  3. 03Both sit bones stay down.
COMMON MISTAKES
  1. 01Levering hard with the arm and forcing the lumbar spine.
  2. 02Lifting one sit bone to gain range.
  3. 03Collapsing the chest as you turn.

Note: Reference material, not a prescription. Load, volume and whether this movement suits you at all depends on your assessment — if something hurts, stop and get it looked at.
