How to perform

§ 02 · Steps
  1. 01

    Sit in the seated crunch machine with your back firmly against the backrest and the pivot aligned with your core.

  2. 02

    Adjust the seat and chest pad or movement arms so you feel a light stretch in your abs at the starting position, and brace your core before each repetition.

  3. 03

    Crunch your upper body forward by bringing your rib cage toward your pelvis without bending at the hips, and keep the movement controlled while your pelvis stays still.

  4. 04

    Squeeze your abs hard at the end of the movement and exhale.

  5. 05

    Slowly return to the starting position while inhaling and maintain tension; do not let the weight stack slam.

What it works

Builds your abs and core control. A stronger core helps with heavy lifts and maintaining good posture.

What it should feel like

You should feel it in your abs, especially at the end of the crunch. It should not be in your neck, arms, or lower back.

Most common mistake

A common mistake is pulling with your arms or bending at the hips. Keep your chin neutral and bring your ribs toward your hips under control.

Tips

§ 05 · Tips

Keep your chin in a neutral position and avoid pulling with your hands; let your abs do the work. Adjust the load so you can keep the movement slow and controlled throughout the entire range of motion.

The seated machine crunch allows targeted loading of the abdominal muscles and a consistent movement path without unnecessary strain on the lower back.
