How to do Decline Sit-Up

Setup

Secure your feet under the padded bars of a decline bench, with the bench angled 15-30 degrees below horizontal. Lie back with your knees bent and place your hands across your chest or behind your head without interlocking fingers.

How to do it

  1. Exhale and curl your torso up by contracting your abs, lifting your shoulder blades first then your mid-back.
  2. Rise until your torso is nearly perpendicular to the floor, keeping your lower back rounded rather than hinging at the hips.
  3. Pause briefly at the top while maintaining tension in your abs.
  4. Lower back down with control until your shoulders touch the bench, keeping constant tension on your core.
  5. Avoid using momentum by maintaining a steady rhythm throughout each rep.

Watch out for

  • Pulling on the neck with interlaced fingers instead of keeping the head neutral and hands relaxed.
  • Using hip flexors to hinge upward rather than curling the spine through abdominal contraction.
  • Dropping back down too quickly and bouncing off the bench instead of controlling the eccentric portion.
