Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Recline on an incline bench, feet firmly planted, holding a dumbbell in each hand with arms extended. Curl the weights upward until your elbows are bent at a 45-degree angle, then slowly lower back down. Maintain a stable core and keep your back pressed against the bench throughout the movement.
Control the descent to enhance bicep activation. Avoid momentum by performing a deliberate, steady motion. Extend your arms completely at the bottom for a greater stretch. Limit the range of motion, stopping before the weights reach your shoulders. Focus on contracting your biceps during the lifting phase.
