Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Start at a pull-up bar with an overhand grip, a bit wider than your shoulders. Engage your core and pull your body up until your chest reaches the bar, then lower yourself with control. This exercise primarily targets your back and biceps.
Extend your range of motion by slightly arching your body during the pull. Build core strength with planks to prevent excessive movement. Prioritize smooth, deliberate movements over speed to optimize muscle activation and avoid injury. Chin-ups are a variation that shifts the focus to your upper back.
