Adjust seat height for 90-degree knee angle. Select appropriate weight. Sit with back against the backrest, feet flat. Grip handles as instructed. Engage core, pulling navel towards spine. Exhale, contract abs to bring chest towards knees, slowly. Pause at peak contraction. Inhale, slowly return to start, controlled. Repeat.
Maintain a slow, controlled pace. Focus on abdominal muscle engagement, avoid arm/leg involvement. Relax your neck. Exhale during contraction, inhale during release. Start with lighter weight, adjust machine for comfort.
