How to perform Russian Sit-up

  1. 1

    Set up

    Sit on the floor with knees bent and feet slightly off the ground. Lean back to create a V-shape with your torso and thighs.

  2. 2

    Create a stable start

    Set the feet and equipment securely, then begin with the ribs stacked over the pelvis.

  3. 3

    Perform the movement

    Rotate your torso from side to side while maintaining the V-position. Keep your core engaged throughout the movement.

  4. 4

    Finish with control

    Pause when the abdominals are shortened, then lower one segment at a time to the start.

Common mistakes

  • Pulling on the neck instead of moving the trunk
  • Bouncing out of the bottom position
  • Racing the lowering phase
  • Using more load than can be controlled

Coaching cues

  • Ribs toward pelvis
  • Exhale through the hardest range
  • Keep the load close
  • Lower under control

Easier variations

  • Short-range curl-up
  • Bodyweight sit-up
  • Reduce the bench angle or band tension

Harder variations

  • Add a pause
  • Increase range gradually
  • Add load while keeping the same tempo

Sets, reps and workout placement

Strength

Use 3-5 sets of controlled, challenging work and stop before technique changes.

Muscle and work capacity

Use 2-4 sets in a repeatable range, adding reps before adding load or difficulty.

Skill and control

Practice low-fatigue sets early in the session with full rest between attempts.

Place this movement after the general warm-up. Skill-heavy versions belong near the start of the workout; loaded strength work should come before high-fatigue accessory work.

Frequently asked questions

What muscles does Russian Sit-up work?

Russian Sit-up primarily uses Rectus Abdominis, Obliques, Obliques. Secondary support comes from Tendinous Inscriptions, Tendinous Inscriptions.

How should I progress Russian Sit-up?

First meet the same range and body position on every repetition. Then add one repetition, a longer hold, less assistance, or a small amount of load rather than changing several variables at once.

When should I stop a set of Russian Sit-up?

Stop when the key positions can no longer be maintained. Sharp pain, numbness, or a sudden loss of control is a reason to stop and reassess rather than push through.
