weighted round arm

Stand with your feet shoulder-width apart and hold a dumbbell in each hand. Bend your knees slightly and hinge forward at the hips, keeping your back straight. Raise your arms out to the sides, keeping a slight bend in your elbows. Continue lifting your arms until they are parallel to the ground. Pause for a moment at the top, then slowly lower your arms back down to the starting position. Repeat for the desired number of repetitions.
