How to Do the Russian Twist

Follow these steps to perform the Russian Twist with correct form:

1Sit on the ground with your knees bent and feet flat on the floor.
2Lean back slightly while keeping your back straight and your core engaged.
3Hold your hands together in front of your chest or hold a weight if desired.
4Lift your feet off the ground, balancing on your sit bones.
5Twist your torso to the right, bringing your hands or weight towards the right side of your body.
6Pause for a moment, then twist your torso to the left, bringing your hands or weight towards the left side of your body.
7Continue alternating sides for the desired number of repetitions.

Muscles & Anatomy

The Russian twist is a seated rotational core exercise where the lifter sits on the floor with the torso reclined at approximately 45 degrees, feet either planted or elevated, and rotates side to side — optionally with a weight held at the chest. The primary targets are the obliques: the internal and external oblique muscles that create rotational force at the trunk. The external oblique on one side works synergistically with the internal oblique on the opposite side to produce each rotation. The rectus abdominis works isometrically to stabilize the spine against the rotational force, and the transverse abdominis maintains intra-abdominal pressure throughout. The hip flexors work isometrically to hold the reclined torso position, especially when the feet are elevated. Because rotation is a fundamental athletic movement pattern — throwing, swinging, changing direction — the Russian twist has high carryover to sports performance and daily function.

Pro Tips for Better Results

1Rotate from the upper body, not just the arms. The rotation should originate at the thoracic spine and be driven by the obliques — not by swinging the arms side to side with the trunk stationary. Hold the weight close to the sternum and feel the obliques contracting on each rotation. If you only feel your arms moving, the movement is entirely wrong.
2Keep your feet slightly off the ground for increased core activation. When feet are planted, the hip flexors assist in stabilizing the torso and the abdominal demand is reduced. Elevating the feet removes this assistance and forces the rectus abdominis and obliques to work harder to maintain the reclined position throughout the set.
3Touch the weight to the floor on each side rather than stopping in the air. A clean touch to the floor ensures full, consistent range of rotation on every rep and provides a repeatable endpoint for tracking progress. Stopping in the air at different points each rep makes it impossible to standardize the range of motion.

Common Mistakes to Avoid

✗ Sitting upright instead of maintaining the 45-degree recline

Fix: The reclined position is what creates hip flexor loading and increases the abdominal stabilization demand. Sitting upright reduces the lever arm of the torso dramatically and makes the exercise much easier without improving the rotational stimulus. Maintain the 45-degree recline consistently throughout all reps and sets.

✗ Using too heavy a weight and losing rotational range of motion

Fix: Heavy weight in the Russian twist tends to reduce the rotation to a very small arc — the arms may move but the trunk barely rotates. The effectiveness of this exercise comes from the range of rotation, not the load. Use a moderate weight that allows genuine thoracic rotation with full range from side to side.

✗ Rocking the hips side to side instead of rotating the thorax

Fix: Hip rocking is a compensation where the pelvis shifts laterally to fake rotation rather than the spine actually rotating. The hips should stay stable and level throughout the movement. Place your attention on the ribcage rotating — the lower body should be as still as possible while the upper body moves.

✗ Performing reps too quickly without controlling the rotation

Fix: Fast Russian twists performed for high rep counts become a momentum exercise that trains neither the obliques nor the rotational control the exercise is designed for. Use a controlled pace where you feel the oblique on the rotating side contracting through the entire arc. Two seconds in each direction is the minimum useful tempo.

How to Program the Russian Twist

Sets & Reps

3–4 sets of 10–20 reps per side. The obliques contain a mixture of fiber types and respond to both moderate-load lower-rep work and high-rep endurance work. For hypertrophy: 10–15 reps with a weight plate or medicine ball. For core endurance and conditioning: 20–30 bodyweight reps per side.

Frequency

2–3 times per week. The obliques recover quickly from rotational work and can be trained frequently without significant recovery cost. However, extremely sore obliques from excessive volume interfere with breathing and spinal stabilization during compound lifts. Moderate consistent volume is more productive than extreme occasional sessions.

Where to Place It in Your Workout

End of any training session. Rotational core exercises should follow all compound movements. Training the obliques before heavy squats, deadlifts, or overhead pressing compromises their isometric stabilizing function during those movements. Program Russian twists as one of the final exercises of any session.

How to Progress

Progress from bodyweight to a light medicine ball or plate, then to a heavier implement. Alternatively, extend the range of motion (deeper rotation), slow the tempo, or elevate the feet for increased difficulty before adding load. A medicine ball slam circuit or cable rotation can provide variety when Russian twists become too easy.

Variations & Alternatives

Weighted Russian Twist (Medicine Ball)

Hold a medicine ball instead of a weight plate. The medicine ball allows the option of slamming it to the floor on each side, which adds a plyometric explosive component. The round shape also allows the ball to roll slightly, creating a small additional stabilization challenge. One of the most popular weighted rotational core exercises in athletic training.

Cable Seated Rotation

Seated on the floor or a bench beside a cable machine, pull the cable across the body in a rotational pattern. The cable provides constant tension through the full range of rotation, unlike free weights which vary in resistance based on lever arm. Superior to the Russian twist for controlled, resistance-consistent rotational training.

Ab Rollout

Not a twist variation, but often programmed together as a complementary core exercise. The ab rollout trains the anterior core in a plank-extension pattern that challenges different aspects of core function than rotation. Pairing Russian twists (rotation) with ab rollouts (anti-extension) creates a comprehensive core training stimulus in minimal time.
