How Iridium Programs This

Iridium leverages the high stability of this machine to program higher RPE targets, allowing you to push the upper chest closer to failure than with free weights. The algorithm tracks sub-muscle group fatigue to ensure your upper chest volume remains within your Maximum Adaptive Volume distinct from flat pressing work. Iridium also monitors anterior deltoid recovery from your 7-day history to confirm that shoulder fatigue will not limit your performance on these sets.

Form Cues

Adjust the seat so the handles align with your upper chest/collarbone
Retract your shoulder blades firmly against the back pad
Keep your elbows tucked at roughly a 45-degree angle
Exhale forcefully as you press the handles upward
Control the weight slowly on the way down for a 2-second count

Don't

Don't let your elbows flare out wide past your shoulders
Don't arch your lower back excessively to lift the weight
Don't allow your shoulders to roll forward at the top of the movement
Don't lock your elbows aggressively at full extension
Don't let the weight stack slam down between repetitions

Common Mistakes

Setting the seat too low or high
Shortening the range of motion
Excessive elbow flaring
Lifting head off the bench
Using momentum to bounce the weight

Muscles Worked

This exercise primarily targets the clavicular head of the pectoralis major (upper chest), helping to build fullness in the upper torso. It heavily recruits the anterior deltoids and triceps as secondary movers to assist in the pressing motion, while the fixed path minimizes the need for stabilizer muscles compared to free weights.
