How Iridium Programs This

Iridium tracks volume specifically for the upper chest sub-group, distinguishing this work from general pectoral fatigue to ensure balanced development. If your 7-day workout history shows recent heavy pressing that may have exhausted your anterior deltoids, the algorithm adjusts RPE targets here to prioritize isolation and metabolic stress over heavy loading.

Form Cues

Set the bench angle between 30 and 45 degrees
Keep your shoulder blades retracted and depressed against the bench
Drive the handles upward and inward in a converging arc
Squeeze your upper chest muscles hard at the peak of the movement
Control the cables slowly on the way down to maximize muscle tension

Don't

Don't let your shoulders roll forward at the top of the press
Don't flare your elbows out excessively wide
Don't rush the lowering phase or let the weight stack slam
Don't press straight up; ensure your hands come together for a peak contraction

Common Mistakes

Setting the bench angle too steep (over 45 degrees)
Allowing shoulders to round forward
Flaring elbows too wide
Rushing the eccentric (lowering) phase
Not bringing hands together at the top

Muscles Worked

This movement specifically isolates the clavicular head of the pectoralis major (upper chest), helping to fill in the upper region of the torso. It recruits the anterior deltoids and triceps as secondary movers, while the cable machine provides constant tension on the muscle fibers throughout the entire range of motion, unlike dumbbells where tension drops at the top.
