Dumbbell one arm lateral raise with support

Stand with your feet shoulder-width apart and hold a dumbbell in one hand, with your palm facing your body. Place your other hand on a stable surface, such as a bench or wall, for support. Keep your back straight and engage your core. Raise the dumbbell out 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 down to the starting position. Repeat for the desired number of repetitions, then switch sides.
