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 knees too much, which shifts the work off the gastrocnemius onto the soleus. Cutting the range short and skipping the deep heel stretch where most of the growth happens. Bouncing the reps instead of lowering under control — kills the time-under-tension on the calves. Rounding the back in the bent-over position, which puts strain on the lower back over volume.
💪 Where you should feel it: Mainly in the Calves.
