Dumbbell standing alternate raise

Stand with your feet shoulder-width apart, holding a dumbbell in each hand with your palms facing your body. Keep your back straight and your core engaged. Raise one dumbbell to the side, keeping your arm straight and your palm facing down. Continue lifting until your arm is parallel to the ground. Pause for a moment at the top, then slowly lower the dumbbell back to the starting position. Repeat with the other arm. Alternate between arms for the desired number of repetitions.
