How can I properly perform a bent arm lateral raise to target my shoulder muscles effectively?

To properly perform a bent arm lateral raise to target your shoulder muscles effectively, stand with your feet shoulder-width apart, hold a dumbbell in each hand, and bend your elbows at a 90-degree angle. Keeping your core engaged, raise your arms out to the sides until they are parallel to the floor, then slowly lower them back down. Focus on using your shoulder muscles to lift the weights, rather than swinging your arms. Repeat for the desired number of repetitions.
