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: Yanking the head and neck forward to start the rep, which strains the neck instead of the abs. Dropping back down quickly and bouncing off the floor instead of controlling the lowering phase. Holding the dumbbell out in front of the chest, which loads the shoulders instead of the abs. Hooking the feet too aggressively under a pad, which lets the hip flexors do most of the work.
💪 Where you should feel it: Mainly in the Keskivartalo.
