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: Swinging the torso to throw the bar up, which transfers work from the biceps to the lower back. Drifting the elbows forward at the top, which turns the curl into a partial front raise. Cutting the range short and not extending the arms fully at the bottom of each rep. Gripping the bar too wide, which shifts tension off the biceps and stresses the wrists.
💪 Where you should feel it: Mainly in the Hauikset.
