Position yourself for this exercise by standing up with a dumbbell in each hand. Place the dumbbells upright on your upper thighs (so that one head of each dumbbell is resting on each thigh). Raise the dumbbells to shoulder height (I do this by kicking up my thighs) and rotate your wrists so that both of your palms are facing forward in order to assume the starting position. In order to execute the exercise, push the dumbbells upwards from the starting position until your arms are locked and the dumbbells are nearly touching over your head. After briefly pausing at the top contracted position, slowly lower the weight back into the starting position. Try to ensure that you are not using leg drive in order to propel the dumbbells upwards. Repeat for the prescribed number of repetitions.
