How Iridium Programs This

Since resistance bands create a variable load curve that is harder to standardize than iron weights, Iridium relies heavily on your RPE feedback to verify you are achieving progressive overload. The algorithm also scans your 7-day workout history for heavy pulling movements to ensure your forearms have sufficient recovery capacity before adding this isolation work.

Form Cues

Hold the handles with your palms facing down (pronated grip).
Keep your elbows pinned to your sides throughout the set.
Squeeze your forearms and biceps hard at the top of the movement.
Lower the band slowly to maximize tension on the forearm muscles.
Keep your wrists straight and aligned with your forearms.

Don't

Don't let your elbows flare out away from your body.
Don't swing your torso to generate momentum to lift the band.
Don't let your wrists curl or flop; keep them neutral.
Don't shrug your shoulders up towards your ears.

Common Mistakes

Using momentum to jerk the band up
Allowing elbows to drift forward
Curling the wrists instead of the forearms
Performing partial reps with limited range of motion
Letting the band go slack at the bottom

Muscles Worked

This exercise primarily targets the brachioradialis in the forearm and the brachialis, a muscle that lies beneath the biceps and contributes to upper arm thickness. By using a pronated (overhand) grip, the biceps brachii is placed at a mechanical disadvantage, forcing the forearms to take on the majority of the load to build grip strength and definition.
