Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Place the parallettes shoulder-width apart on a stable surface while checking the height and spacing to ensure a solid setup before starting. Grip the bars with completely straight arms, pressing down through your palms to depress your shoulders while keeping your neck neutral and your scapulae engaged. Bring your knees up toward your chest to form a ninety-degree angle, keeping your shins parallel to the ground without letting your hips sag or your lower back round. Brace your core tightly and drive the parallettes down into the floor to lift your feet completely off the ground until your hips are slightly above shoulder level. Hold the position for the targeted time while maintaining slow, steady breathing, keeping your shoulders stable, your triceps engaged, and your midline tight throughout the set.
