For this exercise, we'll actually learn how to execute the shoulder press -- standing with palms facing in. You may refer to the GIF before reading the the instructions, if you want the visual first. Happy lifting! (These are also called neutral overhead presses).
1) Hold one dumbbell in each hand. Your elbows should be pointing toward the ground.
2) Turn your wrists so that your palms are facing each other. Press the weights overhead, keeping your elbows close to your body.
3) Press until your arms are fully extended over your head. Return to the starting position.
