Russian Twist

  • Beginner
  • Compound
  • Rep-based
  • Waist

The Russian Twist is a core rotation exercise that targets the obliques and transverse abdominis to improve rotational stability and midsection definition. It challenges the core's ability to maintain a static V-sit position while moving through the transverse plane.

Setup

  1. Sit on the floor with your knees bent and feet flat on the ground.
  2. Lean your torso back at a 45-degree angle, keeping your spine straight and chest open.
  3. Clasp your hands together in front of your chest and lift your feet slightly off the floor to balance on your sit bones.

How to do it

  1. Rotate your torso to one side, bringing your hands toward the floor beside your hip while exhaling.
  2. Inhale as you return to the center position with control.
  3. Rotate to the opposite side, ensuring the movement is driven by your ribs rather than just swinging your arms.
  4. Maintain a steady, controlled tempo, alternating sides for the duration of the set.

Form checklist

  • Keep the spine long and avoid rounding the lower back into a 'C' shape.
  • Ensure the shoulders are rotating fully to engage the obliques.
  • Keep the knees as still as possible to prevent the hips from taking over the movement.
  • Maintain the 45-degree lean throughout the entire exercise to keep the abs under tension.

Pro tips

  • Focus on 'wringing out' your midsection like a towel at the end of each rotation to maximize muscle fiber recruitment.
  • Follow your hands with your gaze to ensure your thoracic spine is actually rotating.

Make it harder

  • Hold a weight plate or dumbbell to increase the rotational load.
  • Straighten your legs into a full V-sit position to increase the lever length and core demand.
