Russian Twist Plus

  • Intermediate
  • Compound
  • Rep-based
  • Waist

The Russian Twist Plus is a dynamic core variation that combines torso rotation with alternating leg extensions to intensely target the obliques and quadriceps. This compound movement improves rotational stability and hip flexor endurance by increasing the lever arm of the lower body.

Setup

  1. Sit on the floor with your knees bent and feet flat, then lean your torso back to a 45-degree angle while maintaining a neutral spine.
  2. Lift your feet off the ground, balancing on your sit bones with your shins parallel to the floor.
  3. Clasp your hands together in front of your chest and pull your shoulder blades back to open the chest.

How to do it

  1. Rotate your torso to the right while simultaneously extending your left leg straight out, hovering it just above the floor.
  2. Exhale sharply as you twist, reaching your hands toward the floor beside your right hip.
  3. Inhale as you return to the center 'V-sit' position, pulling the extended leg back to the starting bend.
  4. Repeat the movement on the opposite side, alternating the leg extension and torso rotation in a fluid, controlled tempo.

Form checklist

  • Keep your chest lifted and avoid rounding your lower back into a 'C' shape.
  • Ensure the rotation occurs at the waist and ribs rather than just moving your arms side-to-side.
  • Keep your neck neutral by following the movement of your hands with your gaze.
  • Maintain a rigid torso angle; do not let your back drop closer to the floor as you tire.

Pro tips

  • Think about 'wringing out' your midsection like a towel to maximize the mind-muscle connection with the obliques.
  • Actively squeeze the quadriceps of the straightening leg to stabilize the pelvis and increase the total-body tension.

Make it harder

  • Slow the tempo to a 3-second eccentric phase and hold the peak rotation for 2 seconds.
  • Keep both legs fully extended in a straight-leg V-sit position throughout the entire set of rotations.
