Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Brace core, retract scapulae. Inhale to lower dumbbell to chest, elbow at 45 degrees, pausing when upper arm is parallel to the ground. Exhale to press dumbbell straight up. Resist rotation, and switch sides after reps.
Focus on driving the weight through your chest muscles to ensure you're engaging the correct muscle groups and avoiding shoulder strain. Keep your elbows tucked in close to your body throughout the movement to protect your shoulder joints and maximize chest activation. Actively brace your core and resist any twisting or rotation of your torso to maintain stability and proper form. Consciously depress your shoulders down and back to create a stable base and prevent rounding of the upper back. Plant your feet firmly on the ground, maintaining a balanced and stable stance to transfer power effectively and avoid unnecessary movement.
