Stand facing the wall bars and place your hands or forearms on the bars at about shoulder height. Step back slightly and lean your chest forward while keeping your arms straight and shoulders relaxed. You should feel a gentle stretch across the front of your chest and shoulders. Hold the stretch with steady breathing, then relax and repeat as needed.
