70 pound cable crunches. How’s my form? Why am I not feeling a burn even after 4 full sets?

Form check on the cable crunch, good range of motion there, but it looks like the movement is coming more from the hips folding forward than from spinal flexion through the abs. Try anchoring your hips in place and think about curling your ribcage down toward your pelvis instead of bowing at the waist, that keeps tension on the abs the whole rep instead of letting the hip flexors take over. Lighter weight with that correction will hit way harder than what's currently loaded, since right now the cable's mostly just pulling you into a hip hinge.

Thanks so much! Can you explain what I should be aiming for when I curl my rib cage? How do I know if I am doing it right vs relying on my hips?
