1) Stand straight holding a pair of dumbbells in your hands with your palms facing your body. Keep a slight bend in your knees, feet at shoulder width, look forward, and slightly arch your back.
2) Exhale and raise the dumbbell with one hand in front of you to your shoulder level. Do not change your palm rotation and your grip.
3) Inhale and slowly lower the dumbbell back to your starting position. Alternate between arms - i.e. one rep left arm, one rep right arm.
