Lower the dumbbells until they are near your ears, with your elbows at about a 90-degree angle.
Pause for a moment at the bottom of the movement, then push the dumbbells back up to the starting position, extending your arms fully but without locking your elbows.
Repeat this movement for the desired number of repetitions while maintaining control of the weights and the movement at all times.
