Take two dumbbells and seat on a flat bench.
Lift the dumbbells to your shoulders. Your palms are facing each other, your elbows point to the sides, not forward.
Press the dumbbells directly upward, at the same time rotating your hands so your palms face forward at the top. Also pull the dumbbells towards each other as you press them. Do not lock your elbows.
Lower the dumbbells to the starting position near your shoulders.
