Brace, exhale, and curl the rib cage toward the pelvis through spinal flexion while keeping the hips relatively still. Pause in the shortened position, then return slowly without allowing the stack to pull the torso backward. The machine crunch trains the rectus abdominis and obliques against adjustable resistance; depending on the design, hip flexors may also contribute. Keep the neck aligned rather than leading with the chin, use a controlled range instead of maximal rounding, and reduce the load if the movement shifts into the hips or lower back.",66,"abdominal",[29],"weight_reps",{"id":14,"slug":15,"name":16,"sortOrder":17,"i18nKey":18},[32],{"id":14,"slug":15,"name":16,"sortOrder":17,"i18nKey":18},[],[],"2026-05-09T00:28:06.432+00:00","2026-08-07T11:03:37.693+00:00","2026-05-09T00:28:07.520+00:00","2026-06-05T00:31:50.179+00:00"]
