Select the appropriate weight of the dumbbells. Stand up straight with a dumbbell in each hand. You should use a neutral grip. Contract your pelvic floor and core while keeping your chest up. Lift the dumbbells so your elbows and shoulders are around 90º. Your hands and elbows should be together.
Open your arms until both hands are in a straight line with your head. Return to the starting position in a smooth movement.TIPS: While your are doing the exercise, move only the shoulder joint, make sure you don't move any other part of your body.
