Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Fasten a rope handle in the lower position on a cable pulley. Turn your back against the pulley, with the cable between your thighs, and take a few steps forward. Bend forward by hinging in your hips, and let the rope handle move backwards between your thighs. Extend your hip again, and return to standing.
Keep feet slightly wider than shoulder-width. Point toes out a bit to open the hips and better target the glutes. Avoid standing with feet too close or too far apart.
