Single Russian Twist
Single Russian Twist Exercise Description
The Single Russian Twist is a seated trunk-rotation exercise performed with body weight to train the obliques and overall core stability. You’ll hold a slightly reclined, neutral spine while rotating the rib cage and shoulders as one unit over a stable pelvis. Primary emphasis is on the external and internal obliques; the rectus abdominis and transverse abdominis brace to maintain position, with assistance from the hip flexors and spinal erectors to control the torso angle. The goal is smooth, controlled thoracic rotation—avoiding excessive lumbar flexion or twisting through the lower back. Keep the movement deliberate, prioritize posture and breathing, and use a comfortable range that allows the pelvis and knees to stay quiet.

How To Do The Single Russian Twist Exercise
‘- Sit on the floor with knees bent, heels lightly planted, and feet hip-width apart.
– Lengthen through the crown of the head; stack ribs over pelvis and brace the abdominal wall.
– Hinge back slightly at the hips until you feel your core engage, keeping a neutral spine (avoid rounding).
– Bring hands together in front of the chest (or arms extended), shoulders down and away from ears.
– Rotate the rib cage and shoulders to one side from the mid/upper back; keep pelvis and legs still.
– Pause briefly, keeping the chin neutral and eyes following the hands.
– Exhale as you rotate; inhale as you return to center.
– Rotate to the opposite side with the same control and posture.
– Keep the range small enough that the lower back stays neutral; do not collapse or bounce.
– If posture falters, reduce the lean angle, keep arms closer to the chest, and focus on controlled rotation.
Single Russian Twist Tips
‘- Sit with knees bent, heels lightly planted, and feet hip-width to create a stable base.
– Lengthen through the crown of your head and stack your ribs over your pelvis before leaning back.
– Hinge back slightly at the hips until you feel your core engage, keeping a neutral (not rounded) spine.
– Keep your shoulders down and away from your ears, with hands together in front of your chest or arms extended.
– Rotate from the mid/upper back so the rib cage and shoulders move as one unit over a stable pelvis.
– Keep your pelvis, knees, and legs as still as possible while the upper body rotates.
– Keep your chin neutral and let your eyes follow your hands as you rotate.
– Exhale as you rotate to the side and inhale as you return to center to support controlled movement.
– Use a small, comfortable range of motion that lets your lower back stay neutral without collapsing or bouncing.
– If your posture starts to falter, decrease the lean angle and keep your arms closer to your chest while focusing on smooth, controlled rotation.
Single Russian Twist Beginner Introduction
The Single Russian Twist is a bodyweight, seated core exercise centered around turning the torso from side to side while in a slightly reclined position. It highlights the side abs, with strong support from the abs, hip flexors, and lower back muscles to hold the upper body at an angle. The upper ribs and shoulders move together as one block, while the hips and legs remain steady, creating a rotational challenge for the core rather than the lower back.
This movement places a big emphasis on control, posture, and breath. The back stays long and aligned, with the chest lifted and the midsection gently braced as the torso rotates right and left from the mid and upper spine. The twist is kept comfortable and measured, so the pelvis and knees stay stable and the lower back does not sag or over-rotate. A smooth breathing pattern—exhaling through the turn and inhaling on the return—supports steady, fluid motion and reinforces core stability throughout.
