Russian Twist: How to Do It Right
Most people do Russian twists by swinging their arms. Here is how to actually rotate through your trunk, plus safer alternatives if twists bother your back.
The Russian twist is a seated core exercise where you lean back slightly and rotate your torso from side to side, often holding a weight. To do it right, the rotation has to come from your ribcage and trunk, not from swinging your arms. A slow twist where your chest turns to face each side is far more effective than fast taps of a weight on the floor.
It's a decent oblique exercise when done with control. It's also one of the most commonly butchered moves in the gym. Here's how to get it right, who might want to skip it, and what to do instead.
What muscles the Russian twist works
The main targets are your internal and external obliques, the muscles on the sides of your waist that rotate and side-bend the trunk. The rectus abdominis works isometrically to hold you in the leaned-back position, and your hip flexors keep you from falling backward.
If you want a full plan for the sides of your waist, see our oblique workout.
How to do a Russian twist
- Sit on the floor with knees bent and heels on the ground.
- Lean back to about 45 degrees with a long, tall spine. Don't slump.
- Hold your hands together at chest height, or hold a light weight close to your body.
- Exhale and rotate your ribcage to one side, so your chest and shoulders turn, not just your hands. Your eyes follow your hands.
- Pause briefly, return to center under control, and rotate to the other side.
- One rotation to each side equals one rep.
Keep your knees still. If they're swaying side to side, your hips are rotating with your torso and your obliques are working less.
Mistakes that ruin the exercise
Swinging the arms
This is the big one. People keep their torso facing forward and just whip their arms or the weight across their body. The weight moves a lot but the trunk barely rotates. Slow down and think about turning your sternum, not your hands.
Rounding the back
Slouching into a C-shape loads the spine in flexion while you twist, which many people find uncomfortable. Sit tall, lean back from the hips, and keep your chest proud.
Going too heavy
A heavy weight held far from your body makes it nearly impossible to rotate with control. Start with bodyweight, then a 2-5 kg plate or ball held close to your chest.
Lifting the feet too early
Feet-up Russian twists look harder but mostly make it harder to balance. Master the feet-down version first.
Speed over range
Fast, tiny twists turn the move into a rhythm game. Slow, full rotations build more strength.
Variations from easiest to hardest
| Variation | Setup | Best for |
|---|---|---|
| Seated twist, upright | Sit tall, minimal lean | Learning the rotation |
| Bodyweight Russian twist | 45-degree lean, feet down | Most beginners |
| Weighted Russian twist | Light plate held at chest | Adding load |
| Feet-elevated twist | Heels off the floor | More anti-extension demand |
| Medicine ball twist with pause | 2-second hold each side | Control and time under tension |
Sets and reps
For most people, 2-3 sets of 8-12 slow reps per side is plenty. Use a load that lets you keep full rotation for every rep. Rest about a minute between sets.
A simple oblique pairing you could use once or twice a week:
- Side plank: 2 x 30-45 seconds per side
- Russian twist (slow, weighted): 3 x 10 per side
- Pallof press: 3 x 10 per side
You can use the interval timer for the side planks and rest periods. If you want a session built from your available equipment, try the ab workout generator.
Is the Russian twist bad for your back?
It's a fair question. The Russian twist combines spinal flexion (leaning back with a rounded posture, if you slump) with rotation, sometimes under load and at speed. Some coaches avoid it for that reason, especially for people with a history of disc problems.
For a healthy person doing slow, controlled reps with a tall spine and a sensible load, it's generally considered reasonable. But if twisting while seated aggravates your back, you lose very little by dropping it. Plenty of other exercises train the obliques well.
If you have back pain or a known spine issue, talk to a doctor or physical therapist before including loaded rotation. Our guide to core training and lower back pain has more background.
Alternatives to the Russian twist
If twists bother you, or you want more effective oblique work, try these:
- Pallof press: trains your obliques to resist rotation. Very back-friendly.
- Cable woodchopper: standing rotation where the hips and trunk turn together, easy to load progressively.
- Side plank: trains the obliques to resist side bending.
- Suitcase carry: walking with a weight in one hand. Simple and brutally effective for the sides.
- Bicycle crunch: adds rotation to a crunch, with less spinal load than a weighted twist.
Many people find a mix of anti-rotation and standing rotation builds stronger obliques than seated twists alone.
Will Russian twists slim your waist?
No exercise burns fat from your waist specifically. Russian twists can strengthen and modestly build the obliques, but fat loss across your whole body is what makes the waist look leaner, and that comes mostly from a calorie deficit. Heavy oblique training can actually add a little muscle to the sides, which some people like and some don't. The waist-to-height ratio calculator is a simple way to track waist changes over time.

FAQ
How many Russian twists should I do?
Two to three sets of 8-12 controlled reps per side is a good target. Quality matters more than volume. If you can do 30 per side easily, add a light weight or slow down.
Should I lift my feet during Russian twists?
Only once you can rotate fully with feet down. Lifting your feet adds a balance and hip flexor challenge, but it doesn't make the oblique work much better if your rotation suffers.
What weight should I use for Russian twists?
Start with bodyweight. Then try a light plate or medicine ball, often 2-5 kg, held close to your chest. Increase only when you can keep full rotation and a tall spine for every rep.
Do Russian twists work your abs or just obliques?
Mostly obliques, with your rectus abdominis working to hold the leaned-back position. For full coverage, add a crunch or leg raise variation for the front of your abs.
Are Russian twists good for beginners?
The bodyweight version with feet down is fine for most beginners. If it bothers your back, start with Pallof presses and side planks instead.
