Instructions

  1. 1Lie down on the floor placing your feet either under something that will not move or by having a partner hold them. Your legs should be bent at the knees.
  2. 2Elevate your upper body so that it creates an imaginary V-shape with your thighs. Your arms should be fully extended in front of you perpendicular to your torso and with the hands clasped. This is the starting position.
  3. 3Twist your torso to the right side until your arms are parallel with the floor while breathing out.
  4. 4Hold the contraction for a second and move back to the starting position while breathing out. Now move to the opposite side performing the same techniques you applied to the right side.
  5. 5Repeat for the recommended amount of repetitions.

About Russian Twist

Seated, torso leaning back and feet lifted or planted, you rotate the trunk from one side to the other, bringing your hands, or a weight, close to the floor. The Russian twist emphasises the obliques and trunk rotation while the rectus abdominis and lower back work as stabilisers. The rotation should come from the trunk, not just the arms. It is an intermediate exercise: start with no load and feet down, then lift the feet or add a plate to raise the difficulty once the movement is well controlled.

lightbulbExecution tips

  • lightbulbRotate the torso, not just the arms from side to side
  • lightbulbKeep the back braced and slightly leaned back
  • lightbulbPause briefly on each side to squeeze the obliques
  • lightbulbLift the feet only once your core bracing is solid
  • lightbulbControl the speed rather than trying to rush through reps

warningCommon mistakes

  • warningMoving only the arms without rotating the torso
  • warningRounding and relaxing the lower back during rotation
  • warningGoing too fast and losing control of each rep
  • warningHolding the breath instead of exhaling on the twist
  • warningSlamming the weight or hands onto the floor on each side, a sign of poor control

tuneVariations and alternatives

  • tuneWeighted Russian twist – add a plate or dumbbell to overload the rotation.
  • tuneFeet-down Russian twist – a more accessible version for beginners, keeping the feet on the floor.
  • tuneCable Russian twist – constant resistance from a low pulley instead of free weight.
  • tuneMedicine-ball slam twist – add a bounce off the floor for a more explosive version.
  • tuneRussian twist on a swiss ball – adds an instability component at the pelvis.

person_checkWho it's for and level

The Russian twist suits lifters of all levels who want to strengthen the obliques and rotational capacity of the trunk, an aspect often neglected by pure flexion exercises like the crunch. It particularly suits athletes in sports requiring rotational power, such as golf, tennis, baseball or combat sports. Beginners can start with feet down and no load to learn the rotation pattern before adding weight or lifting the feet. It stays less suitable for people with active lower-back pain, since the repeated rotation can aggravate certain issues. It's also a staple of functional fitness and CrossFit training for its simple execution and effectiveness. Swimmers and paddlers find it particularly useful, since trunk rotation is central to their sports.

shieldSafety and precautions

The Russian twist requires solid lower-back control to stay safe over time. Always keep the trunk braced and avoid letting the back round or arch during the rotation. People with lower-back pain or a disc herniation should avoid this exercise or consult a professional before trying it, since combined rotation and flexion can increase pressure on the intervertebral discs. Always start with feet down and no load to confirm good technique before increasing the difficulty. If a heavy load makes you lose your back position, immediately reduce the weight rather than continuing with poor posture. A proper hip and trunk warm-up before the session reduces the risk of lower-back discomfort during the rotation.

calendar_monthWhere to place it in your program

Place the Russian twist mid or late in an ab session, for 3 sets of 16 to 24 reps (8 to 12 per side). It pairs ideally with a flexion exercise like the crunch and a lower-ab exercise like the leg raise, to cover the whole abdominal region in one session. Increase the difficulty gradually: first by lifting the feet, then by adding load, rather than stacking both at once. Two to three sessions a week are enough to progress well. Add it at the end of an ab session or even in a circuit with other rotational exercises to vary the working angles. A logical progression is to first increase the reps, then the load, rather than both at once.

helpFrequently asked questions

Do I need to lift my feet?

No, keep the feet down when starting; lift them only once your core is strong.

Is it risky for the back?

Done well and without excess load it's safe; brace the core and avoid rounding the lower back.

With or without weight?

Without weight to learn the movement and really feel the obliques; add a plate or a light dumbbell afterwards. Keep the load controlled: the quality of the rotation matters more than the weight.

What weight should I start with?

A light 2-5 kg (5-10 lb) plate or a medicine ball is enough; the quality of the rotation matters more than the load.

Does the Russian twist slim the waist (spot reduction)?

No, it strengthens the obliques but doesn't burn fat locally; a slimmer waist depends on your overall body-fat level.

Does the Russian twist suit golf-specific training?

Yes, it's an excellent exercise for developing the rotational trunk power useful for the swing.

Can I do it with a kettlebell?

Yes, the kettlebell's shape offers a comfortable grip and makes it easy to increase the load.

How long before seeing results on the obliques?

With 2 to 3 regular sessions a week, noticeable strengthening appears in 4 to 6 weeks, with visibility mainly depending on body-fat level.
