2. Raise the 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.
4. Perform the movement for the required number of reps and once finished, repeat the steps with the other arm.
