Deep stretch curls that build the lower bicep.
Let the arms hang fully back for the stretch, don't shorten the bottom.
Reclining on the incline with an EZ-bar sends your arms hanging behind your torso, loading the biceps in their most lengthened position, where curls do their most valuable work. The angled EZ grips let both arms share one implement without the wrist strain a straight bar can bring in that stretched position. It earns its place as the two-handed version of the stretch curl: the same lengthened loading as incline dumbbell curls, but with a fixed bar that keeps both arms honest and lets you focus purely on the squeeze.
Same stretch, different trade-offs. The bar links both arms so neither can slack off and the weight is easier to control in the stretched position, while dumbbells allow free wrist rotation and expose side-to-side gaps. Rotate both over time.
Wrist comfort. With your arms hanging behind your body, a fully supinated straight-bar grip cranks on the wrists and elbows. The EZ-bar's angled grips take that tension off so the biceps stay the limiting factor.
Yes, it quietly deletes the stretch you came for. Drifting elbows turn the bottom of the rep into a rest position. Keep the upper arms hanging back and still, and end each rep at a full hang, not a comfortable halfway point.
