Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Attach a handle to the cable machine at chest height. Stand sideways, feet shoulder-width apart. Extend arms fully, parallel to the floor. Engage your core and rotate your torso away from the machine, keeping arms extended. Rotate until facing away, then slowly return. Switch sides.
Maintain a slight bend in your knees for balance. Rotate through your torso, not your arms. Engage your core to protect your lower back. Control the movement speed. Exhale during rotation, inhale on return. Keep shoulders level.
MuscleTrain is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
