Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Start on a decline bench, holding dumbbells with palms facing each other at your hips. Press the weights upwards until your arms are straight, then slowly lower them back to chest height. Repeat the movement to build upper body strength.
Keep a slight bend in your elbows to protect the joints. Angle the dumbbells outward slightly to target the chest muscles more effectively. Grip the weights firmly to stabilize your shoulders. Tighten your core and draw your shoulder blades together. Maintain a stable base by keeping your feet flat on the bench.
