Ab crunch machine: how to do it right

The crunch machine flexes your torso against a resistance you can adjust. It lets you progress your abs like any other muscle.

Step by step

  1. Adjust the seat and sit with your feet under the rollers or on the footrests.
  2. Grab the handles or rest your arms on the pads.
  3. Curl your torso forward, rounding your back as if bringing your ribs to your hips.
  4. Return slowly without letting the weight touch down.

Tip: Breathe out as you curl your torso.

Common mistakes

Pulling with your arms

Your arms only hold on; the movement comes from your abs.

Using your hips

If the movement comes from bending at the hips, your hip flexors work more. Think about curling your torso.

Going fast

Control the return.

Sets and reps

Guide ranges. Start with a weight where the last rep is hard but your technique holds.
