Iron Cross
The Iron Cross is an elite gymnastics ring exercise where you hold your body suspended with arms extended horizontally to the sides in a 'T' shape. It requires immense straight-arm strength and stability, targeting the chest, shoulders, and biceps.
Iridium restricts this advanced isometric to sessions where your per-muscle recovery scores indicate your chest and anterior deltoids are fully fresh. To quantify progress on a static hold, the AI tracks duration relative to your bodyweight and adjusts set volume to prevent exceeding your Maximum Recoverable Volume for the week.
Form Cues
- Lock your elbows completely throughout the hold
- Depress your shoulders down away from your ears
- Maintain a hollow body position with core engaged
- Squeeze the rings tightly to generate tension
- Keep your head neutral and look straight ahead
- Don't allow your elbows to bend even slightly
- Don't shrug your shoulders up towards your ears
- Don't arch your lower back
- Don't let the rings drift behind your body
- Don't relax your core tension
Common Mistakes
- Bending elbows to compensate for weakness
- Shrugging shoulders excessively
- Breaking the hollow body position
- Rolling shoulders forward aggressively
- Attempting the hold without proper tendon conditioning
Muscles Worked
The Iron Cross primarily targets the sternal head of the pectoralis major and the anterior deltoids, which must generate massive force to keep the arms adducted against gravity. It also heavily recruits the biceps brachii and elbow flexors to maintain the straight-arm lock, along with the latissimus dorsi and core for stabilization.
