Sit on the leverage crunch machine and flex your spine to curl the torso toward the hips. The movement primarily engages the abdominal muscles.
How to do the Machine Crunch#
- Adjust the seat so your arms bend about 90° and your triceps rest comfortably on the machine pads.
- Grasp the handle with a firm grip and keep your legs relaxed.
- Exhale and contract your abs to curl the weight, bringing your torso forward while allowing the legs to move slightly closer to your upper body.
- Hold the top position briefly while maintaining tension in your abdominals.
- Inhale and slowly lower the weight back to the starting position under control.
Muscles worked#
Common mistakes#
- Using the arms to pull the weight instead of initiating the curl with the abs.
- Actively lifting the legs instead of keeping them relaxed.
- Performing the movement with fast, jerky momentum.
- Allowing the lower back to arch during the exercise.
