How to Do Russian Twists (Core Rotation)
Russian twists target your obliques and rotational core strength — useful for sports and a strong midsection. Here’s how to do them without straining your back.
How to do them
- Sit with knees bent, feet on or just off the floor, leaning back to about 45°.
- Hold your hands together (or a light weight) at your chest.
- Rotate your torso to one side, then the other, under control.
- Keep your chest up and back straight — rotate from the core, not by flopping side to side.
Do them safely
- Move slowly and with control — speed and momentum increase strain and reduce the benefit.
- Keep your spine long, don’t round or wrench your back.
- Start bodyweight; add light weight only once form is solid.
- Feel free to keep feet down to reduce the demand.
- Pair with other ab exercises for a complete core.
Russian twists train rotation — move slowly, rotate from the core, keep the back straight. Momentum and a rounded back are the mistakes to avoid.
Quick answers
What do Russian twists work?
The obliques and rotational core strength, with the rest of the abs assisting. They’re useful for sports and midsection strength.
Are Russian twists bad for your back?
Done slowly with a straight spine, they’re fine. Fast, momentum-driven twisting with a rounded back is what risks strain — control the movement.
