Sit on an incline bench with a dumbbell in one hand, resting on your thigh. Lie back on the bench and position the dumbbell at shoulder level, palm facing forward. Press the dumbbell upward and slightly inward, extending your arm fully. Pause for a moment at the top, then slowly lower the dumbbell back to the starting position. Repeat for the desired number of repetitions, then switch to the other arm.
