Sit upright on a bench and hold a pair of dumbbells just outside shoulder-width apart (Palms facing forward) and elbows flexed to your sides.
2. Raise one dumbbell vertically by extending your arm overhead and pressing through your palm while keeping your forearm perpendicular to the ground.
3. Once your arm is fully extended, pause for a moment and slowly lower the dumbbell back to the starting position and repeat the steps with the other arm.
