How Iridium Programs This

Iridium categorizes this as a shortened-position isolation movement and uses it to balance your bicep development if your 7-day history is heavy on neutral or lengthened-position curling. Due to the high stability of the machine, the system often programs this later in workouts to safely increase local muscle volume without taxing your systemic recovery. Iridium tracks 1RM estimations and RPE trends specifically for this machine to ensure consistent progressive overload.

Form Cues

Adjust the seat so your armpits rest comfortably over the top edge of the pad
Keep your triceps pressed flat against the cushion throughout the movement
Squeeze your biceps hard at the top of the contraction
Lower the handles slowly until your arms are fully extended
Keep your wrists neutral and aligned with your forearms

Don't

Don't lift your elbows off the pad as you curl the weight up
Don't lean your upper body backward to help move the load
Don't let your shoulders shrug up towards your ears
Don't hyperextend or snap your elbows at the bottom of the rep

Common Mistakes

Lifting elbows off the pad
Using momentum to swing weight
Setting the seat too low
Shortening the range of motion

Muscles Worked

This exercise primarily targets the biceps brachii, with a specific emphasis on the short head due to the arms being positioned in front of the body. It effectively isolates the upper arm flexors while engaging the forearms for grip stability.
