Seated Thoracic Twist
The seated thoracic twist is a bodyweight mobility exercise targeting the thoracic spine and lower back, performed while seated. It involves rotating the upper body side to side with the arms crossed to improve thoracic mobility, stretch the spinal rotators, and engage the obliques.
How to do it
- Sit upright in your chair with your feet flat on the floor.
- Cross your arms over your chest, placing each hand on the opposite shoulder.
- Engage your core and slowly rotate your upper body to the right as far as comfortably possible, keeping your hips facing forward.
- Hold the twisted position for 2-3 seconds, then rotate back through center and continue to the left.
- Continue alternating sides in a controlled motion for the desired number of repetitions.
Form cues
- Sit tall with your spine elongated.
- Keep your hips glued to the chair.
- Cross arms firmly over your chest.
- Rotate from your ribcage, not your neck.
- Move slowly and with control.
Breathing: Inhale to prepare, and exhale deeply as you rotate into the twist to allow for better range of motion.
Common mistakes
- Moving the hips: This shifts the rotation to the lower back instead of the thoracic spine.
- Leading with the head: This strains the neck muscles rather than targeting the upper back.
- Rounding the shoulders: This limits your range of motion and reduces the effectiveness of the stretch.
- Holding your breath: This creates tension and prevents your muscles from fully relaxing into the twist.
Muscles worked
Primary: lower back. Secondary: obliques, traps.

Should I feel this in my lower back?
You may feel a gentle stretch, but it should never be sharp or painful. Focus on twisting from your mid-back.
How often can I do this?
You can perform this mobility exercise daily, especially if you spend long hours sitting.
What if I can't rotate very far?
That is perfectly normal. Focus on quality of movement rather than depth, and your range will improve over time.
