Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Hold a dumbbell vertically by your side and slowly lower it towards your head by bending your elbow. Focus on feeling the stretch in your triceps as you descend. Return to the initial position, extending your arm fully as you breathe out.
Choose a weight that allows for 12 repetitions with good form. Keep your elbow close to your head and relatively still during the movement. Tighten your core to stabilize your body. Prioritize proper form rather than lifting heavy weights.
