Dumbbell Lateral Raise Tips When performing dumbbell lateral raises, there are two small tips to help reduce trapezius activation. First, use a thumb-up grip (partial grip) to reduce forearm involvement, allowing the shoulder muscles to engage more. Second, maintain shoulder depression and stabilize the scapula throughout the movement to prevent overactivation of the upper trapezius, keeping the focus on the lateral deltoids. #shoulderworkouts #fitness | Ariel Yu
