Start standing with your feet shoulder-width apart, holding a dumbbell in each hand with a neutral grip (your palms should be facing in toward your thighs) and your arms extended. This is your starting position.
Inhale and bend your elbows, and curl the dumbbells in toward your chest, keeping your elbows in close contact with the sides of your body.
On an exhale, extend your elbows as you press the dumbbells above your head, ensuring that your arms are in line with your ears on either side of your head.
On an inhale, lower the dumbbells back to your shoulders and then extend them so that you are holding the weights back by your side and in the starting position. This counts as one rep.
