Continue lowering the weights until your elbows are at a 90-degree angle and the dumbbells are just above your forehead.
Pause for a moment at the bottom of the movement, then use your triceps to return the dumbbells back to the starting position.
Repeat this movement for your desired number of repetitions, making sure to keep your upper arms still and only moving your forearms.
