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: Just swinging the arms side to side without rotating the torso — loads the shoulders, not the core. Rounding the back instead of staying tall through the spine, which strains the lower back. Letting the feet drop to the floor every rep, which breaks the constant core tension. Rushing the tempo instead of pausing on each side — turns a controlled twist into momentum-only work.
💪 Where you should feel it: Mainly in the Keskivartalo. The Keskivartalo assist.
