Sharing the way to shape beautiful arm:

1.   Sit on a study chair with your feet flat on the floor.  Hold a dumbbell in each hand with your arms extended down at your sides and your palm facing forward.  Your back should be straight and your eyes facing forward.

2.   Keeping your upper body stable, blend your elbow, and curl the weights up towards your shoulders.  Without hesitating, rotate your wrist so your palms are facing out in front of you.  Press the weight over your head.  Maintain the same distance between the dumbbells as you lift.  Stop just before your arms are completely straight.  the weights should be overhead and in front of your body.  Pause, slowly revers the movement, and lower the weights.

Do it everyday until you shape-up your beautiful arms.
