Dumbbell Russian Twist
This weighted progression of the Russian twist puts a dumbbell in your hands, forcing the obliques to control real load as the torso rotates side to side. It belongs to trainees who have mastered slow, full-turn bodyweight twists and need external resistance for the obliques to keep adapting. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.
Muscles worked
Sets & reps by goal
| Goal | Sets × Reps | Rest |
|---|---|---|
| Strength | 4 sets x 3-6 reps per side with a 1-sec freeze at each end | 90 sec - 2 min |
| Muscle | 3 sets x 9-12 reps per side | 60-90 sec |
| Endurance | 2 sets x 18-27 reps per side with a light dumbbell | 30-45 sec |
Level — Intermediate
Intermediate — the load is only justified once slow, full-rotation bodyweight twists are boringly easy.
Proper form — 5 cues
- Hold a dumbbell by its ends at your breastbone, elbows soft.
- Lean back to the 45-degree line with a long, unrounded spine.
- Rotate the chest and dumbbell together toward one hip, moving as one block.
- Touch or approach the floor with the dumbbell, pause, and rotate to the far side.
- Keep the dumbbell close to the body — the further it drifts, the more the shoulders take over.
Breathing: Exhale as the dumbbell travels to each side, inhale returning through the centre.
The 3 mistakes Maddy corrects most
Common questions
How heavy should the dumbbell be for Russian twists?
Light enough to freeze motionless beside each hip for a full second. That single test filters out almost every unsuitable weight: most trainees start well between two and six kilograms, and even strong lifters rarely need more than ten. The obliques respond to controlled rotation under load, not to how big the dumbbell looks in the mirror.
When should I progress from bodyweight to weighted twists?
When bodyweight versions are genuinely strict and no longer challenging: full shoulder turns, slow tempo, feet grounded or floated without form change, and sets of 15-plus per side feeling routine. Add the lightest available dumbbell first and cut your reps roughly in half, rebuilding volume as control at the new load proves itself.
Weighted Russian twist vs cable rotation — which is better for obliques?
Cables and bands provide smoother resistance that stays tense through the whole arc, and standing rotations are generally friendlier to the lower back — so where equipment allows, they are the more refined choice. The weighted twist wins on simplicity: one dumbbell, no anchor, anywhere. Strict execution matters more than which of the two you pick.
