The Russian twist is a simple rotational core move — sit, lean back, and rotate side to side to train the obliques. Here's how to do it with good form, the muscles it works, the mistakes to avoid, and how to program it.
The Russian twist is a rotational core exercise that primarily works the obliques, with the rectus abdominis and deep core holding you in the leaned-back position. You sit with your knees bent, lean your torso back to about 45 degrees, and rotate side to side — optionally holding a weight plate or dumbbell. It's a beginner-friendly way to train trunk rotation, and you can make it harder by adding load or lifting your feet off the floor.
The Russian twist trains the core through rotation. The obliques do the twisting, while the rectus abdominis and deep core hold your leaned-back torso in place and the hip flexors keep you seated.
| Role | Muscles | What they do in the lift |
|---|---|---|
| Primary mover | Obliques | Rotate the trunk from side to side |
| Assisting | Rectus abdominis | Holds the torso leaned back against gravity |
| Assisting | Transverse abdominis | Braces the trunk and keeps the spine tall |
| Stabilizers | Hip flexors, spinal erectors | Maintain the seated, leaned-back position |
Step-by-step form. Rotate through your trunk, not just your arms, and keep the spine long rather than rounded.
If you want to train trunk rotation or the obliques with a different setup or difficulty, these are the common swaps:
The Russian twist works well in a core circuit or as an oblique-focused accessory. General starting points:
| Goal | Sets × reps | Notes |
|---|---|---|
| Oblique strength | 3 × 10–16 | Add a plate or dumbbell, controlled tempo, rotate through the trunk (count each side) |
| Endurance | 2–3 × 16–24 | Bodyweight or light load, steady pace, keep the spine tall |
| Frequency | 2–3× / week | Progress by adding load, lifting the feet, or slowing the tempo |
Training the obliques builds the muscle, but a defined midsection also depends on your body-fat level and nutrition — abs are built in the kitchen too. See nutrition for lifting and cutting for that side of it.
Log every set of Russian twists — reps and any weight held — in LiftHero, and it charts your progression so you can see your reps or load climbing over the weeks. Add rest-timer holds between sets, drop it into a core circuit, and save it into a routine so it's ready the next time you train. LiftHero records what you log; it doesn't diagnose your form.
It mainly works the obliques, which rotate the trunk, along with the rectus abdominis and deep core that hold you leaned back. The hip flexors help maintain the seated position.
No. Bodyweight is fine for beginners. Adding a plate or dumbbell lets you progressively overload, but keep the load light enough that you rotate through the trunk rather than swinging the arms.
Both work. Keeping the heels down is easier and more stable. Lifting the feet off the floor removes a base of support and makes the core work harder to keep you balanced.
They build and strengthen the obliques, but whether they're visible also depends on body-fat level and nutrition — abs are built in the kitchen too. Training the muscle and managing body fat both matter.
Most lifters do about 3 sets of 10 to 20 total reps, counting a twist to each side as one rep. Add a light weight or slow the tempo before piling on endless reps.
