Muscles worked

Primary

  • Abs
  • Obliques

Secondary

  • Erector spinae

Equipment

  • Leverage machine

Setup

  1. Adjust the seat height so the chest pad is at mid-chest level and your feet are flat on the floor or footrests.
  2. Sit firmly with your hips and lower back pressed against the seat back or pads.
  3. Grasp the handles lightly and engage your core to stabilize your spine.
  4. Set the weight and align the machine's starting position to your preferred side.

How to do it

  1. Exhale as you rotate your torso to one side, initiating the movement from your obliques rather than your arms.
  2. Rotate as far as your natural range of motion allows while keeping your hips stationary.
  3. Inhale as you slowly return to the starting position with a controlled 2-second eccentric phase.
  4. Complete all reps on one side before switching to the opposite direction.

Form checklist

  • Keep your hips and pelvis glued to the seat; do not let them rotate with your upper body.
  • Maintain an upright, tall posture throughout the movement without slouching.
  • Avoid pulling with your arms or shoulders; they should remain fixed as your torso moves.
  • Keep your head and neck neutral, following the rotation of your chest.

Pro tips

  • Imagine your ribcage rotating around your spine like a corkscrew to maximize oblique engagement.
  • Hold the peak contraction for one second at the end of the rotation to intensify the mind-muscle connection.

Make it harder

  • Implement a 3-second slow eccentric (return) phase to increase time under tension.
  • Add a 2-second isometric hold at the point of maximum rotation.
