How Iridium Programs This

Iridium tracks the increased bicep contribution of the reverse grip and counts it toward your weekly arm volume landmarks to prevent redundant isolation work. Because the bent-over posture creates high systemic fatigue, the algorithm checks your 7-day history to avoid scheduling this exercise if your lower back is still recovering from recent heavy squats or deadlifts.

Form Cues

Hinge at the hips until your torso is at a 45-degree angle
Grip the barbell with palms facing up (supinated)
Drive your elbows back tightly against your ribs
Squeeze your shoulder blades together at the top
Keep your core braced and spine neutral throughout

Don't

Don't round your lower back at any point
Don't jerk your torso upright to generate momentum
Don't let your elbows flare out wide away from the body
Don't curl your wrists excessively to move the weight
Don't stand too upright; keep the tension on the back

Common Mistakes

Using excessive momentum to lift the bar
Rounding the lumbar spine
Standing too vertically due to heavy weight
Pulling with the biceps rather than the back
Hyperextending the wrists

Muscles Worked

This movement primarily targets the latissimus dorsi and middle trapezius to build back thickness. The underhand (supinated) grip heavily recruits the biceps and allows the elbows to travel closer to the body, placing greater emphasis on the lower portion of the lats compared to overhand variations.
