10 Arm-Sculpting Dumbbell Exercises to Build Muscle

Muscles bent-over reverse fly works: back of shoulders and upper back

• Stand with your feet hip-width distance apart with a dumbbell in each hand. Bend your knees slightly, and keeping your back flat, bend forward at the hip joint. This is the starting position.
• Exhale and lift both arms out wide, maintaining a slight bend in the elbows and squeezing your shoulder blades together.
• With control, lower the dumbbells back to the starting position. This completes one rep.
