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 as you curl, which turns the movement into a half-rep front raise. Standing on too narrow a section of the band, which makes the tension uneven between the two arms. Rushing the eccentric and letting the band snap your hands back down — you lose half the time-under-tension. Leaning back to swing the weight up, which shifts work from the biceps to momentum and the lower back.
💪 Where you should feel it: Mainly in the Hauikset.
