An advanced calisthenic exercise combining an iron cross hold with a crunch movement. This extremely challenging movement requires significant upper body strength and core stability.

Instructions

  1. Sit on a bench and position your hands on either side of your body with palms down for support.
  2. Lean back slightly and extend your arms out to the sides at shoulder height.
  3. Press through your hands to lift your torso and legs slightly off the bench, creating tension across your chest and shoulders.
  4. Maintain the horizontal arm position while engaging your core.
  5. Perform a crunch motion by bringing your chest toward your hips while maintaining the arm position.
  6. Keep constant tension in your chest, shoulders, and core throughout the movement.
  7. Return to the starting position in a controlled manner.
  8. Repeat for the desired repetitions or hold time.

Tips

  • This is an advanced exercise; master basic crunches and chest strength first
  • Maintain constant horizontal arm tension without dropping the arms
  • Core stability is essential to prevent lower back strain
  • Breathing rhythm is important; exhale during the crunch phase
  • Progress gradually as this movement requires significant strength

Recommended starting values
