How Iridium Programs This

Iridium scans your 7-day workout history to detect significant volume load on the pectorals and anterior delts. When fatigue scores for these specific sub-muscle groups are elevated, this stretch is programmed to address tightness and support recovery. The duration of the hold is automatically adjusted to respect your available workout time and warmup preferences.

Form Cues

Place your forearm flush against the wall with your elbow slightly above shoulder height
Step the leg closest to the wall forward into a slight lunge
Engage your core to keep your ribcage down and back flat
Rotate your torso away from the wall slowly until you feel a gentle pull
Breathe deeply into the chest cavity throughout the hold

Don't

Don't allow the shoulder to shrug up toward your ear
Don't arch your lower back to create false range of motion
Don't force the stretch into a range that causes sharp pain
Don't bounce or perform ballistic movements
Don't let the elbow slide down below shoulder level

Common Mistakes

Shrugging the shoulder upward
Hyperextending the lumbar spine
Rotating too aggressively
Holding the breath
Placing the elbow too low

Muscles Worked

This exercise primarily isolates the pectoralis major and pectoralis minor, muscles that are notoriously tight in modern populations. Secondarily, it stretches the anterior deltoid and the biceps brachii, helping to facilitate better scapular retraction and shoulder health.
