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: Bending and straightening the elbows mid-rep, which sneaks the triceps and traps into the lift. Pulling the dumbbells back like a row, swapping rear-delt isolation for mid-back rowing work. Shrugging the shoulders up at the top, which trades rear-delt work for trap engagement. Loading too heavy, which forces swinging form and removes the strict isolation the bench enforces.
💪 Where you should feel it: Mainly in the Shoulders.
