Barbell Seated Twist
- Intermediate
- Compound
- Rep-based
- Waist
The Barbell Seated Twist is a core isolation exercise that targets the obliques and transverse abdominis through controlled spinal rotation. By sitting on a bench, you fix the pelvis in place, forcing the core muscles to drive the rotation without assistance from the lower body.

Setup
- Sit at the end of a flat bench with your feet planted firmly on the floor, shoulder-width apart.
- Place a barbell across your upper traps (high bar position), holding it with a wide overhand grip for stability.
- Sit tall with a neutral spine and pull your shoulder blades back to create a stable shelf for the bar.
How to do it
- Exhale and slowly rotate your torso to one side as far as your mobility allows while keeping your hips glued to the bench.
- Inhale as you return to the center starting position with a controlled, 2-second tempo.
- Exhale and rotate to the opposite side, ensuring your head and neck move in unison with your shoulders.
- Maintain a rhythmic, alternating pattern, focusing on the squeeze in your side-abs at the end of each turn.
Form checklist
- Keep your hips and knees facing forward; do not let your legs shift or slide on the bench.
- Maintain a perfectly upright posture; avoid rounding your lower back or leaning forward.
- Rotate from the mid-back and waist, not by pulling the bar with your hands.
- Keep the movement slow and deliberate to eliminate momentum and protect the spine.
Pro tips
- Focus on the mind-muscle connection by imagining you are wringing out a wet towel with your midsection.
- Engage your glutes and press your feet into the floor to create a 'rooting' effect that stabilizes the lower body.
Make it harder
- Add small weight plates to the ends of the barbell to increase the rotational inertia and resistance.
- Incorporate a 2-second isometric hold at the peak of each rotation to maximize oblique recruitment.
