How Iridium Programs This

Since this instability variation demands high coordination, Iridium checks your recovery and fatigue scores to confirm you have the capacity for stabilization before assigning it. The system credits this volume toward your middle chest landmarks while monitoring sub-muscle fatigue to ensure prior core work doesn't limit your pressing performance. Iridium also scales your rep performance against your current body weight to accurately track progressive overload.

Form Cues

Grip the sides of the BOSU dome firmly with wrists stacked under shoulders
Brace your core and squeeze your glutes to maintain a rigid plank position
Lower your chest until it nearly touches the top of the dome
Keep your elbows angled about 45 degrees from your torso
Exhale forcefully as you drive through your palms to return to the start

Don't

Don't allow your hips to sag toward the floor or pike upwards
Don't flare your elbows out to 90 degrees
Don't let your head drop forward; keep your neck neutral
Don't rely on momentum or bounce off the dome at the bottom
Don't let your wrists roll outward or collapse

Common Mistakes

Hyperextending or sagging the lower back
Performing half-reps without touching the chest to the dome
Flaring elbows excessively wide
Excessive wobbling due to lack of core tension
Jutting the chin forward to reach the dome

Muscles Worked

This exercise primarily builds the pectoralis major and triceps while placing significant demand on the anterior deltoids. Because the surface is unstable, it aggressively recruits the rotator cuff muscles for shoulder stability and the rectus abdominis to prevent the torso from twisting or collapsing.
