Try This Arm Workout For Beginners, Designed by a Personal Trainer

Strengthen your upper back and shoulders with this dumbbell arm exercise. This one works tiny (but important!) muscles in your back and shoulders, so you may need to choose a smaller weight.

• Stand with your feet hip-width apart with a dumbbell in each hand. Bend your knees slightly, and keeping your back flat, bend forward at the hip joint. Hold the dumbbells with straight arms just in front of your knees. 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. Be careful not to arch your back.
• With control, lower the dumbbells back to the starting position. That's one rep.
• Do 10 reps.
