Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Begin standing with a shoulder-width stance, holding dumbbells with an overhand grip. Inhale as you lift the weights upward, extending your arms until they're parallel to the floor, keeping a slight bend in your elbows. Exhale while slowly lowering the dumbbells back to the starting position.
Begin with a manageable weight to prioritize good technique. Maintain a neutral spine and avoid arching your back. Control the weight’s descent for optimal muscle engagement. Prevent bouncing at the peak of the movement. Focus on squeezing your shoulder muscles as you lift.
