Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand with feet shoulder-width apart. Raise arms to shoulder height, elbows bent at 90 degrees. Lift right knee towards left elbow, twisting torso slightly. Return to start, then repeat with left knee towards right elbow. Alternate sides in a rhythmic motion, maintaining control.
Engage your core for balance. Prioritize controlled movements over speed. Exhale as you lift your knee, inhale as you return. Start slowly to master coordination. Relax shoulders, avoid neck tension.
