Reverse Fly Holding a dumbbell in each hand with palms up, stand with knees slightly bent. Keeping your back flat, bend forward at the hip joint. Exhale and raise both arms out to the side, maintaining a slight bend in the elbows and squeezing your shoulder blades together. Then, with control, lower the dumbbells back toward the floor. Complete three sets of 12 reps. Image Source: POPSUGAR Studios
