Russian Twist: Correct Form, Variations and Safety Tips
How to do Russian twists properly for stronger obliques: setup, rotation, breathing, common mistakes, feet-up and weighted versions, and who should avoid them.
By Ayoub Farid · · 3 min read
The Russian twist is one of the most popular oblique exercises, and one of the most often done badly: arms flailing side to side while the torso barely moves. Done right, it builds real rotational strength.
How to do a Russian twist
- Sit on the floor, knees bent, heels on the floor.
- Lean back to about 45°, chest lifted, spine long (not rounded).
- Clasp your hands in front of your chest.
- Rotate your ribcage to one side so your hands move beside your hip.
- Return to center and rotate to the other side.
- Breathe out as you rotate.
Your eyes and chest should follow your hands. If only your arms move, you're not twisting.
Common mistakes
- Rounded back: sit taller, lean back less
- Arms doing the work: rotate from the ribs
- Too fast: use a steady, controlled pace
- Too heavy: start without weight
Variations
| Level | Version |
|---|---|
| Beginner | Feet on the floor, no weight |
| Intermediate | Feet lifted, no weight |
| Advanced | Feet lifted, holding a dumbbell or medicine ball |
| Advanced+ | Weighted with legs straight and lifted |
Sets and reps
Two to three sets of 16–30 total twists (both sides). AbBlitz has several versions in its oblique library, including weighted and feet-up variations.
Is the Russian twist bad for your back?
Some experts argue repeated loaded spinal rotation isn't ideal, especially for people with disc problems. For most healthy people, controlled body-weight twists are fine. If you have back issues, swap for anti-rotation exercises like the Pallof press or side plank, and see lower back pain during ab workouts.
Pair it with
- Bicycle crunches for more oblique work
- Dead bugs for stability
- A full oblique workout
Muscles worked
The Russian twist trains the internal and external obliques through rotation, while the rectus abdominis holds your leaned-back position and the hip flexors support your legs (especially with feet lifted). The erector spinae keep your back from rounding. It's mainly an endurance and coordination exercise for the obliques.
Tempo and range
- Range: rotate until your hands are beside your hip, not until your shoulders face the floor
- Tempo: about one second per side for body weight, slower with load
- Pause: a brief stop at each side removes momentum
A medicine ball tap on the floor beside your hip is a good range marker, but don't slam it.
A 5-minute oblique set with twists
- Russian twist (feet down): 20 total
- Side plank: 20 s per side
- Russian twist (feet up): 16 total
- Bicycle crunch: 20 total
Rest 30 seconds and repeat.
Alternatives if twists bother your back
- Pallof press with a band
- Side plank variations (guide)
- Bird dog (guide)
- Standing woodchop with a light load
These train the obliques without repeated loaded spinal rotation.
Frequently asked questions
What do Russian twists work?
The obliques mainly, plus the rectus abdominis and hip flexors.
Should my feet be up or down?
