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 the elbows mid-rep so the fly turns into a sloppy press and brings the triceps in. Going too heavy and dropping fast into the stretch, which strains the front shoulders. Clanking the dumbbells together at the top instead of squeezing the chest just short of contact. Skipping the bottom of the range so the chest never gets the stretch the fly is meant for.
💪 Where you should feel it: Mainly in the Chest.
