Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Sit with feet on the platform, knees slightly bent. Grasp the handle with a wide, palms-down grip, arms extended. Pull the handle towards your torso, retracting your shoulder blades until elbows are at your sides. Pause, squeezing shoulder blades. Slowly return to the starting position.
Maintain a neutral spine. Engage back muscles, not arms. Keep your torso stable. Exhale on the pull, inhale on the return. Adjust seat height for proper arm alignment.
