How to do the Lever Seated Crunch
CoreAbsMachineBeginner
The lever seated crunch machine gives you a guided resistance curve that challenges your abs through their full range of motion, making it an ideal starting point for building real core strength. Consistency on this movement builds the foundational abdominal control that carries over to every lift you do.

Step-by-step
- Sit tall, secure the pad across your upper chest, and plant your feet flat on the footrest
- Exhale sharply and curl your ribcage down toward your hips, not just your head toward your knees
- Pause for one count at peak contraction before allowing the machine to guide you back
- Return slowly under control, stopping just before the weight stack touches to keep tension on the abs
Common mistakes
- Using your hip flexors to drive the movement instead of your abs, fix this by consciously thinking about shortening the distance between your sternum and your navel
- Letting the machine snap back between reps, which bleeds tension and reduces stimulus, fix this by taking a full two seconds on the return phase
- Gripping the handles and pulling with your arms, which shifts load off the core, fix this by resting your hands lightly and initiating every rep from your midsection
Pro tip — At the bottom of each rep hold the contraction and try to breathe out fully, that forced exhale activates the deep transverse abdominis and makes the squeeze significantly more intense than simply holding your breath.
