Seated Spinal Twist
What Is the Seated Spinal Twist?
Seated Spinal Twist is an isolation exercise that primarily targets the back and glutes and also stretches the sides of the waist and the neck. It is a beginner-level movement performed sitting on the floor with one leg straight and the other knee bent, its foot planted across the straight leg, while the upper body turns toward the bent knee with one elbow hooked around it and the other hand on the floor behind.
It is a static stretch that takes the spine into rotation, and it is most often used to ease the stiff, locked-up feeling in the back that long hours of sitting leave behind. Because it is done sitting and needs no equipment, it fits easily into a cool-down after training, a mobility routine on a rest day or a short break from a desk, and it is one of the standard shapes in yoga classes as well.
Most of the turn comes from the middle and upper back, because the lower back allows only a small amount of rotation, so the stretch is felt along the muscles beside the spine and across the side of the waist. Hugging the bent knee in toward the chest and across the body adds a stretch to the glute and outer hip on that side, and turning the head to look over the shoulder carries the twist into the neck. Folding the bottom leg in as well, with its heel beside the opposite hip, turns the shape into the yoga pose Half Lord of the Fishes, which most people find a tighter twist. The Lying Spinal Twist and the Lying T-Spine Rotation Stretch rotate the spine lying down and let gravity do more of the work, while the Seated Lower Back Stretch rounds the spine forward instead of turning it.
It suits almost anyone who wants a more mobile back, from people who sit for most of the day to athletes in sports that turn the trunk, such as golf, tennis and throwing. Tight hamstrings or hips can make it hard to sit up straight with one leg out, so sitting on a folded blanket or cushion, or wrapping the arm around the knee instead of hooking the elbow outside it, is a good place to start. If the glutes are the main target, the Pretzel Stretch and the Seated Piriformis Stretch work the hip more directly.

Instructions
- Sit on the floor with both legs straight in front of you and sit tall on your sitting bones.
- Bend your right knee and cross your right foot over your left leg, planting it flat on the floor on the outside of your left thigh, near the knee.
- Keep your left leg straight with the toes pointing up.
- Place your right hand on the floor just behind your right hip and press lightly through it to lift your chest.
- Breathe in and lengthen up through the top of your head.
- Breathe out and turn your upper body to the right, hooking your left elbow on the outside of your right knee with the forearm upright and the palm open.
- Turn your head last to look over your right shoulder, keeping your chin level.
- Keep both sitting bones on the floor and feel the stretch along your back, the side of your waist and the outside of your right hip.
- Hold for 20 to 30 seconds, sitting taller as you breathe in and turning a little further only as you breathe out.
- Turn your head and then your chest back to the front, straighten your right leg and repeat on the other side, 2 to 4 times per side.
Common Mistakes
Slumping the lower back
Rounding the back while you turn loads the lower spine and shrinks the twist, so sit tall first and raise your hips on a cushion if you cannot.
Leading with the head
Snapping the head around first strains the neck and makes the twist look deeper than it is, so turn from the middle of the back and let the head follow last.
Cranking with the elbow
Using the elbow against the knee as a lever forces the spine past the range it can control, so let the arm hold the position rather than pull you deeper.
Lifting a sitting bone
Letting one buttock rise off the floor turns the pelvis along with the chest, so the spine twists less and the position becomes unstable.
Leaning back on the support hand
Sinking weight into the hand behind you tips the torso backward and rounds the lower back, so keep the hand close to the hip and press lightly to sit taller.
Holding the breath
Holding your breath keeps the trunk muscles braced against the stretch, so breathe slowly and turn a little further only as you breathe out.
Injuries
Seated Spinal Twist is a low risk exercise when performed with proper technique. The parts most likely to complain are the lower back if you slump and round as you turn or force extra range with the arm, the neck if you lead the twist with your head or crank it to its limit, and the front of the hip on the bent-leg side if the knee is pulled across the body harder than the hip allows.
Sit tall on both sitting bones before you turn, and raise your hips on a folded blanket or cushion if your lower back rounds. Turn slowly as you breathe out, starting from the middle of the back, and turn your head last. Use the hooked elbow and the hand behind you to hold the position, not to lever yourself deeper, and unwind just as slowly when you finish.
People with osteoporosis or low bone density are usually advised to avoid deep twists, and twisting with a rounded spine in particular, so keep the turn small and upright or ask a clinician first. If twisting brings on or worsens pain in your back or down a leg, as it can with a disc problem, skip the stretch and have it checked. After a hip replacement, crossing the knee over the body and bending the hip deeply are often restricted for a period, so follow your surgeon's precautions before trying it. To make it easier, wrap the arm around the knee instead of hooking the elbow outside it, or use the Lying Spinal Twist. To go further, fold the bottom leg in so its heel rests beside the opposite hip.
Stop if you feel a sharp or pinching pain in the back or the front of the hip, tingling or numbness in a leg, or dizziness.

Frequently Asked Questions
- Q: Which way should I twist?
Turn toward the bent knee. With the right knee up and the right foot crossed over the left leg, turn to the right, hook the left elbow outside the right knee and place the right hand on the floor behind you.
- Q: Is this the same as the Half Lord of the Fishes yoga pose?
Not quite. In the full Half Lord of the Fishes pose (Ardha Matsyendrasana) the bottom leg is bent too, with its heel tucked beside the opposite hip, and keeping that leg straight, as here, is the usual modification for tighter hips and knees.
- Q: How long should I hold it?
Hold each side for 20 to 30 seconds and repeat it 2 to 4 times, so you build up about 60 seconds per side. Older adults often do better with longer holds of 30 to 60 seconds.
- Q: Is it good for lower back pain?
It often helps with the general stiffness that comes from sitting, as long as the twist stays gentle and upright. If turning makes your pain worse or sends it down a leg, stop and have the back checked by a clinician.
- Q: Do twists detox your organs?
No. The liver and kidneys clear waste through their own cellular processes, and a twist cannot wring them out. What it does is stretch the muscles around the spine and hip and move the spine through rotation.
- Q: What if I cannot sit up straight with one leg out?
Sit on a folded blanket or cushion so your hips are higher than your knees, which lets the pelvis tilt forward and the back lengthen. You can also bend the bottom knee slightly until your hamstrings loosen up.
