Band Kneeling Crunch
- Beginner
- Compound
- Rep-based
- Waist
The Band Kneeling Crunch provides constant tension throughout the range of motion to effectively isolate the rectus abdominis. By using a resistance band, you can easily adjust the load to build core strength and abdominal thickness without the spinal compression of heavy weighted machines.

Setup
- Loop a resistance band around a high point on a power rack.
- Kneel on the floor facing away from the anchor point, positioned far enough forward to create initial tension.
- Grasp the band with both hands and pull it down so your hands are positioned against your temples or upper chest.
- Position your knees hip-width apart and sit back slightly, but keep your hips high and locked in place.
How to do it
- Exhale and contract your abdominals to curl your torso downward, bringing your elbows toward your mid-thighs.
- Focus on rounding your spine and 'tucking' your ribcage toward your pelvis rather than hinging at the hips.
- Pause for one second at the bottom of the movement to emphasize the peak contraction.
- Inhale as you slowly return to the starting position, resisting the band's pull to maintain control.
Form checklist
- Keep your hips stationary; do not sit back onto your heels as you crunch.
- Ensure the movement comes from spinal flexion (rounding the back), not pulling with the arms.
- Maintain a tucked chin to keep the neck in a neutral, safe position.
- Keep your hands fixed relative to your head throughout the entire set.
Pro tips
- Think about trying to touch your sternum to your belly button to maximize the shortening of the abdominal fibers.
- Maintain a slight glute squeeze to stabilize the pelvis, which prevents the hip flexors from taking over the movement.
Make it harder
- Increase the distance from the anchor point to create higher peak tension at the bottom of the rep.
- Incorporate a slight diagonal rotation at the bottom of the crunch to increase oblique recruitment.
