Dumbbell standing alternating tricep kickback

Stand with your feet shoulder-width apart, holding a dumbbell in each hand. Bend your knees slightly and hinge forward at the hips, keeping your back straight. Extend your arms straight back, keeping your elbows close to your body. Pause for a moment at the top, then slowly lower the dumbbells back to the starting position. Repeat with the other arm, alternating sides with each repetition.
