This page tells you what the machine is. Step-by-step instructions, common mistakes and a video of the movement are in the Luio app — the video shows the range of motion that text cannot describe.
⚠️ Most common mistake: Letting the elbows drift forward like a regular curl, which removes the long-head bias. Using too much weight, which forces the body to swing and breaks the dragging path of the bar. Cutting the bottom range short and not fully straightening the arms between reps. Rounding the shoulders forward to chase the bar up, which loads the front delts instead.
💪 Where you should feel it: Mainly in the Hauikset.
