Russian Twist
The Russian Twist is a seated core exercise that improves control and rotation strength by moving the upper body side to side.

Muscles Worked: Russian Twist
The Russian Twist mainly works your abs, especially the obliques, because they turn your torso and stop you from wobbling as you rotate side to side. Your deeper core muscles also brace to keep your spine steady while your hips and legs stay in position. That mix makes it more than just a “twisting” move, since your midsection has to create motion and control it at the same time. You should feel your sides and midline working hard, and research on core training supports the general role of these muscles in stabilizing and controlling trunk movement during exercise (Saeterbakken et al., 2019).
Technique and form
How to perform the Russian Twist
- Sit on the floor with your knees bent and feet flat on the ground, elevating your upper body to create a V-shape with your thighs.
- Extend your arms straight in front of your chest with hands clasped together or holding a weight.
- Engage your core muscles by drawing your navel toward your spine and slightly lean back until you feel your abdominals activate.
- Lift your feet a few inches off the ground while maintaining balance through your sitting bones, creating tension in your midsection.
- Inhale deeply and on the exhale, rotate your torso to the right, bringing your hands or weight toward the floor beside your hip.
- Maintain a tall spine and avoid collapsing through the chest or shoulders during the rotation.
- Return to center with control, then rotate to the left side while keeping your feet elevated and core engaged.
- Continue alternating sides in a controlled manner, exhaling on each rotation and inhaling as you return to center.
Important information
- Keep your back straight throughout the movement – avoid rounding your shoulders or hunching forward.
- If you're a beginner, start with feet on the floor and work up to elevated feet as your core strength improves.
- Control the movement rather than using momentum – slower, more deliberate twists provide better core engagement.
- If you experience any lower back pain, reduce the range of motion or keep your feet on the ground to decrease the difficulty.
Is the Russian Twist good for muscle growth?
Yes — the Russian Twist can help build your core, especially your obliques, if you make it hard enough and keep tension on the muscles instead of rushing reps. Research on core training suggests both isolated and integrated core exercises can improve trunk muscle function, which supports including direct ab work like twists when your goal is a stronger, more developed midsection (Saeterbakken et al., 2019).
- Direct oblique tension — This exercise puts the sides of your waist under load while you rotate and while you stop the weight from pulling you back. That second part matters because the muscles are working even between turns, not just at the end of each rep.
- Easy to progress — You can start with bodyweight, then hold a medicine ball and slowly increase load, reps, or total sets. That makes progressive overload simple without needing a machine or a big setup.
- Long time under tension — Sets usually last longer than heavy compound lifts, so your core spends more time working without a break. If you slow the turn and pause briefly each side, the exercise becomes much more effective for muscle growth.
- Useful as a focused core add-on — Russian Twists fit well after big lifts because they train rotation without creating much whole-body fatigue. They also pair well with moves like Bicycle Crunch or a loaded russian-twist-medicine-ball variation when you want more total ab volume.
Programming for muscle growth
Do 2-4 sets of 12-20 reps per side with 45-75 seconds rest, 2-4 times per week. Use slower reps and a full side-to-side turn you can control, because the abs respond better to hard, clean reps than fast sloppy ones. Once bodyweight sets feel easy, add a medicine ball or extend the set before adding more weekly volume.

FAQ - Russian Twist
The Russian Twist primarily engages the obliques (side abdominals) while also activating the rectus abdominis (six-pack muscles) and transverse abdominis (deep core). Additionally, it works the hip flexors and erector spinae as stabilizing muscles during the rotational movement.
For an easier variation, keep your feet on the floor or perform the movement with bent knees. To increase difficulty, elevate your feet completely off the ground, extend your legs, increase the rotation range, or add weight (medicine ball, dumbbell, or weight plate).
The most common mistakes include rounding the lower back instead of maintaining a straight spine, moving only the arms rather than rotating from the torso, rushing through repetitions, and using momentum instead of controlled movement. Focus on initiating the twist from your core while keeping your chest up.
Incorporate Russian Twists 2-3 times weekly as part of your core training, allowing at least 48 hours between sessions for muscle recovery. Start with 2-3 sets of 10-15 rotations per side, gradually increasing volume as your core strength improves.
Russian Twists can place strain on the lower back if performed incorrectly. If you have existing back problems, start with a modified version keeping feet on the floor, maintain proper form with a neutral spine, and consider consulting a physical therapist or fitness professional before adding this exercise to your routine.
