Hold a couple of dumbbells on the front of your thighs as you stand with a completely straight torso. The palms of your hands should be facing your thighs. While ensuring that your torso stays in a stationary position, lift one of the dumbbells to your front with a slight bend in your elbow. Continue to raise up the dumbbell until your arm is parallel to the floor. Throughout the entire motion, your palms should remain facing downwards. Once your arm is parallel to the floor, lower it back to the starting position under control, and then perform a repetition with the opposite hand. Repeat for the prescribed number of repetitions. This exercise can be performed either one hand at a time or both hands at the same time.
