Set up gymnastics or suspension rings at about shoulder height and grasp the handles. Lean back with your body straight and core engaged, keeping your feet forward to create resistance. With a slight bend in your elbows, pull your arms outward and backward in a reverse fly motion, squeezing your shoulder blades together at the top. Slowly return to the start under control.
Log your ring reverse fly sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
