Front raises are an isolation exercise that primarily target the anterior deltoids, which are the front of your shoulders. However, other muscles such as the lateral deltoids, upper chest muscles, trapezius, pectoralis major, biceps, serratus anterior, and wrist extensors are also worked to a lesser extent. The lateral deltoids are involved more than the rear deltoids. Front raises can help to build shoulder strength, improve shoulder mobility, and tone your upper body. It is important to use proper form and a weight that is challenging but allows for correct form to be adhered to, as performing front raises with bad form can lead to injury.
