Spine Twist (Seated)
The seated spine twist is a Pilates bodyweight exercise targeting the obliques and abdominal muscles. It involves rotating the torso from a seated position with arms outstretched, developing spinal mobility, waist definition, and rotational core strength.
How to do it
- Sit tall on the mat with your legs extended and feet flexed, slightly wider than hip-width.
- Extend your arms out to the sides at shoulder height.
- Inhale to lengthen your spine, then exhale and rotate your torso to the right.
- Pulse twice to the right, deepening the rotation without collapsing the spine.
- Return to center and repeat on the left side.
- Continue alternating for the desired number of repetitions.
Form cues
- Sit tall and lengthen your spine.
- Keep your hips grounded on the floor.
- Rotate from your ribcage, not your neck.
- Keep your arms at shoulder height.
- Pulse twice with control.
Breathing: Inhale to sit tall and prepare, exhale deeply as you rotate and pulse to engage the core.
Common mistakes
- Slumping the shoulders: This reduces the effectiveness of the core engagement.
- Moving the hips: Keeping hips still ensures the rotation happens in the spine.
- Forcing the range: Pushing too hard can strain the lower back.
- Holding your breath: Proper breathing helps maintain core stability.
Muscles worked
Primary: obliques. Secondary: abs, lower back.

Should I feel this in my lower back?
You should feel a gentle stretch, but if you feel sharp pain, reduce the intensity of your twist immediately.
What if my legs are tight?
You can keep your knees slightly bent to help you sit up straighter and keep your pelvis neutral.
How often can I do this?
This is a mobility exercise; you can include it in your daily warm-up or as part of a dedicated mobility session.
