Cable Kneeling Crunch
Kneeling for a cable crunch anchors the hips in place, so the abs have to do the work of flexing the spine rather than the hip flexors pulling the torso down toward the legs. That makes it a more targeted ab exercise than most weighted crunch variations, which often let the hip flexors quietly take over. Rounding through the upper back, not just bending forward, is what actually shortens the abs under load.
