Hold a couple of dumbbells by your side as you stand with a completely straight torso. The palms of your hands should be facing you. While ensuring that your torso stays in a stationary position, lift the dumbbells to your side with your elbows slightly bent until your arms are nearly, but not quite, parallel to the floor. As you perform this motion, tilt your hands slightly forward (like you are pouring water into a glass). Once your arms are nearly parallel to the floor, lower the dumbbells back to the starting position under control. Repeat for the prescribed number of repetitions. This exercise can be performed either standing up or sitting down.
