Exercise guide

Band Seated Twist

  • Beginner
  • Compound
  • Rep-based
  • Waist

The Band Seated Twist is a core isolation exercise that targets the obliques and transverse abdominis through controlled rotation. By sitting on a bench, you stabilize the pelvis, ensuring the rotational force is generated primarily by the abdominal muscles rather than the hips.

Muscles worked

Primary

  • Abs
  • Obliques

Secondary

  • Erector spinae
  • Glutes
  • Quadriceps

Equipment

  • Resistance band

Setup

  1. Secure a resistance band to a power rack at chest height.
  2. Sit sideways on a flat bench so the anchor point is to your side, with feet flat on the floor and knees at a 90-degree angle.
  3. Grip the band handle with both hands, extending your arms straight out in front of your chest.
  4. Sit tall with a neutral spine, engaging your core before starting the movement.

How to do it

  1. Exhale as you rotate your torso away from the anchor point in a smooth, controlled arc.
  2. Keep your arms straight and your hips glued to the bench to ensure the rotation comes from your waist.
  3. Inhale as you slowly return to the starting position, resisting the band's pull to maintain tension.
  4. Perform a full set on one side before repositioning the bench to work the opposite side.

Form checklist

  • Keep your shoulders down and away from your ears.
  • Ensure your head and neck follow the rotation of your torso.
  • Maintain straight arms throughout the entire range of motion.
  • Keep your lower body completely still; do not let your knees shift.

Pro tips

  • Focus on 'pulling' with the oblique furthest from the anchor point to maximize muscle fiber recruitment.
  • Pause for one second at the end of the rotation to emphasize the peak contraction of the obliques.

Make it harder

  • Increase the resistance by scooting further away from the power rack.
  • Slow down the eccentric (return) phase to a 3-second count to increase time under tension.
