Barbell Seated Twist

The barbell seated twist rotates the torso against the resistance of a bar across the shoulders, training the obliques through a seated, stable base. Because the legs are out of the movement, the rotation has to come entirely from the trunk. Keep the reps controlled and moderate in range, since a loaded twist at end-range rotation is where the lower back tends to complain.

How to Do the Barbell Seated Twist

1. Sit on a flat bench, feet flat on the floor and knees bent.
2. Hold a barbell with both hands out in front of your chest, elbows slightly bent.
3. Brace your core and rotate your torso slowly to one side, keeping your spine straight.
4. Hold briefly at the end range, then rotate back through to the starting position.
5. Perform the same rotation toward the opposite side.
6. Perform for your targeted rep count, focusing on a deliberate tempo and maximum tension in the abs.

Technique & Form Tips

Focus on trunk flexion, rotation, or anti-movement stability as required by your specific variation. Maintain the suggested pelvic and spinal orientation to keep tension focused on the abdominal area throughout each repetition or hold.

Common Mistakes to Avoid

• Copying the wrong trunk action: Follow the demonstrated movement. A held plank, rotation and crunch require different actions rather than the same repeated trunk curl.
• Lower back arching: Keep the spine controlled to prevent the lower back from hyperextending under the load.
• Excessive speed: Perform movements with deliberate control rather than relying on rapid, bouncing motions.

How to Breathe During This Exercise

Maintain a steady breathing rhythm during the effort.

Comfort and Control

Choose a load and range you can control. Stop if the movement causes pain. If discomfort persists, stop and ask a qualified professional about an appropriate exercise and range.

General guidance: Mayo Clinic on weight-training technique. Follow the specific movement steps above for this variation.
