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: Lifting the forearms off the thighs, which lets the biceps take over instead of isolating the forearms. Using too much weight and shortening the range so the bar barely moves at the wrist. Skipping the fingertip roll at the bottom, which cuts out half the forearm and grip work. Rushing the tempo and bouncing the reps, which removes the time-under-tension that builds the forearms.
💪 Where you should feel it: Mainly in the Hauikset.
