Stand with feet about shoulder-width apart and hold a resistance band with both hands. Keep a slight bend in your elbows and a stable core, then pull your arms outward and back so they move to your sides, squeezing your shoulder blades together at the top. Return slowly under control, focusing on feeling the work in your rear shoulder and upper back muscles. This helps improve shoulder posture and strength with minimal equipment.
Log your band reverse fly sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
