Russian Twist

How to perform it

1. 1Preparation and positioning. Sit with the knees bent and the feet planted for the beginner bodyweight standard used here. Lean the trunk back only as far as the pelvis and spine can remain controlled.
2. 2Starting position. Hold the hands together in front of the chest and keep the spine long rather than collapsing into a deep lumbar round. Set the ribs over the pelvis before the first rotation.
3. 3Rotation phase. Rotate the ribcage as one unit toward one side while the pelvis and feet remain relatively quiet. The arms follow the trunk; they do not swing independently to create range.
4. 4End position. Reach the end of the controlled rotation without forcing the shoulder or lumbar spine into a large twist. Pause briefly when the trunk reaches the defined side position.
5. 5Return and alternate. Return through the center under control and rotate to the opposite side. Keep the movement smooth and do not bounce through the midline.
6. 6Breathing and bracing. Breathe continuously and maintain moderate abdominal tension throughout the rotation. Avoid a maximal breath hold or an exaggerated abdominal draw-in that changes the trunk position.
7. 7Valid repetition. Count one repetition when the trunk reaches both sides with the feet remaining planted and the pelvis controlled. If the chosen plan counts each side separately, record that convention consistently.

Common mistakes

• Moving only the arms

  Fix: Rotate the ribcage and let the arms follow instead of swinging the hands from side to side.

• Excessive lumbar flexion

  Fix: Reduce the lean and keep the trunk long enough to control the rotation without collapsing.

• Using momentum

  Fix: Pause briefly at each side and return through the center without bouncing.

• Lifting the feet too early

  Fix: Keep the feet planted until the trunk control standard is stable; progress the lever separately later.

Safety

• The combined seated lean and rotation may be poorly tolerated by some people with spinal or hip symptoms; use a smaller range or choose an anti-rotation alternative.
• Keep the feet planted for the beginner version to reduce balance demands; do not force a lifted-foot variation because it looks harder.
• Do not add load until the unloaded trunk position and rotation are repeatable without symptom escalation.
• Acute, radiating, electric, or progressive symptoms require stopping and appropriate assessment rather than a technique workaround.

Progressions & alternatives

• regressionShort-range Seated Trunk Rotation— Use a more upright trunk and smaller arc to learn controlled rotation without losing pelvic position.
• progressionWeighted Russian Twist— Add external load only when bodyweight rotation remains controlled and symptom-free within the defined range.
• progressionFeet-elevated Russian Twist— Increase the balance and trunk-control demand by removing the foot support; this is a meaningful but not universally necessary progression.
• alternativePallof Press— Train trunk resistance to rotation with an externally scalable cable load when repeated spinal rotation is not the preferred task.
