Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand with feet shoulder-width apart, holding dumbbells at shoulder height with an overhand grip. Engage your core, press dumbbells upward until arms are fully extended (slight elbow bend). Pause at the top, then slowly lower to the starting position. Repeat.
Maintain a tight core. Control the tempo throughout the movement. Keep wrists straight and aligned. Avoid flared elbows. Exhale on the press, inhale on the descent. Start with lighter weights.
