Movement instructions

Set up, move with control, and reassess.

1
Select a light resistance and sit down on the ab machine placing your feet under the pads provided and grabbing the top handles. Your arms should be bent at a 90 degree angle as you rest the triceps on the pads provided. This will be your starting position.
2
At the same time, begin to lift the legs up as you crunch your upper torso. Breathe out as you perform this movement. Tip: Be sure to use a slow and controlled motion. Concentrate on using your abs to move the weight while relaxing your legs and feet.
3
After a second pause, slowly return to the starting position as you breathe in.
4
Repeat the movement for the prescribed amount of repetitions.

Technique guidance

Breathe, avoid common faults, and train safely.

Breathing

Exhale through the abdominal effort and inhale during the controlled return. Keep the neck relaxed and do not hold your breath.

Common mistakes

Pulling on the neck or leading the movement with the head.
Letting the lower back lose its intended position.
Rushing repetitions or holding the breath.

Safety

Use a stable setup and a load or resistance you can control through a comfortable range.
Stop if you feel sharp pain, dizziness, or feel unwell.
Adjust the seat, pads, and range stops to fit before adding resistance, and keep hands clear of moving parts.

Ab Crunch Machine

The ab crunch machine is a great way to isolate your abdominal muscles while maintaining a safe, guided range of motion. Unlike standard floor crunches, the machine allows you to easily adjust the resistance (weight), which is critical for progressively overloading your core muscles just like any other muscle group.

Why use the Ab Crunch Machine?

Adjustable Resistance: You can add or reduce weight depending on your current strength level.
Support: It often provides support for your back and neck, reducing the strain on these areas that sometimes occurs with floor exercises.
Isolation: The guided motion ensures your abs are doing the work, minimizing the involvement of hip flexors if set up correctly.

Tips for Success

Don't pull with your arms. The handles are there for stability. Your core should be doing the crunching.
Exhale on exertion. Breathe out forcefully as you crunch forward. This helps fully contract the abdominal muscles.
Control the eccentric phase. Don't let the weight slam back down. Control the movement on the way back to the starting position to maximize time under tension.
