Bent-Over Reverse Fly Work your upper back and the area between your shoulder blades with this low-impact exercise. Be careful not to hunch your shoulders or build any tension in your neck. Start in the standing position with a dumbbell in each arm. Bend your knees and bend at the waist, keeping your back straight and your abdomen tight. Bring your arms out in front, and then extend your arms back squeezing your shoulder blades. Return to starting position. Continue slow and controlled for 15-20 repetitions.
