Sitting on a bench pins your hips and legs in place, so the barbell in your hands can only move if your trunk actually rotates. The long bar also magnifies any wobble at its ends, which is useful feedback: an empty or lightly loaded bar is plenty, and smooth turns beat fast ones.
How to do the Barbell Seated Twist
- Sit on a flat bench with your feet flat on the ground and your knees bent.
- Hold a barbell with both hands in front of your chest, keeping your elbows slightly bent.
- Engage your core and slowly twist your torso to one side, keeping your back straight.
- Pause for a moment at the end of the twist, then slowly rotate back to the starting position.
- Repeat the twist to the other side.
- Continue alternating sides for the desired number of repetitions.
Tip: Pivot on the back foot and let the hips turn with the shoulders so the rotation is shared across the whole body.
Muscles worked
Primary
Abs · Core
The obliques rotate the torso and resist the return, and you should feel the side of the waist tighten on each side as you turn.
Secondary
- Obliques — The obliques are the prime movers, with the internal and external obliques on opposite sides working together to turn the trunk.
- Spine — The deep spinal muscles control the rotation and keep the movement smooth.
Common mistakes
- Twisting from the lower back — the rotation should come from the mid back and hips; keep the lower back neutral and let the hips turn with you on standing variations.
- Using the arms to swing — on cable and band rotations the arms stay locked out in front of you and the torso does the turning.
- Rushing the reps — control the return and pause briefly at the end range on each side instead of bouncing back and forth.
- Loading barbell twists heavy — gravity barely resists rotation, so keep barbell twists light and controlled, and use a cable or band when you want real rotational load.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Strength | 3 × 8–12 | 60 s |
| Endurance | 2–3 × 15–25 | 45 s |
Rotations work at the end of a session with the other core work, or as a warm-up before throws and rotational sports. Superset cable rotations with a cable side bend or pull-through on the same stack.

Frequently asked questions
What muscles does the Barbell Seated Twist work?
The Barbell Seated Twist primarily works the abs. It also involves the obliques and spine, which assist the movement and stabilise the joints.
Is the Barbell Seated Twist good for beginners?
It is rated intermediate, so it suits people who already train regularly. Beginners can still do the Barbell Seated Twist with light load and a spotter or coach watching the first few sessions; if it feels awkward, pick an easier variation from the alternatives below first.
What can I do instead of the Barbell Seated Twist?
If you cannot do the Barbell Seated Twist, try the Russian Twist, the Weighted Stability Ball Twist or the Weighted Russian Twist. Each of them trains the abs through a similar movement, so you can swap them in without changing the rest of the workout.
How many sets and reps should I do?
It depends on your goal. For the Barbell Seated Twist, a sensible starting point is strength: 3 × 8–12 with 60 s rest; endurance: 2–3 × 15–25 with 45 s rest. Train it at the end of a session or pair it with a lower-body lift as active rest.
