Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Sit on a bench with dumbbells, palms forward. Feet flat, shoulder-width apart. Press dumbbells upward, rotating wrists to face inward at the top. Pause, extend arms (not locked). Lower slowly, rotating wrists back to palms forward. Repeat.
Engage your core. Control the movement; avoid momentum. Keep elbows slightly bent. Focus on smooth wrist rotation. Choose a weight allowing proper form. Exhale on the press, inhale on the lower.
