Cable chest flies are an effective strength training exercise that targets the pectoralis major muscles in the chest. This exercise is performed using a cable machine, which allows for constant tension throughout the movement. To execute the exercise, stand in the center of the machine, grasp the handles with both hands, and pull them together in front of your chest while keeping a slight bend in your elbows. The movement emphasizes the stretching and contracting of the chest muscles. It is important to maintain proper form by keeping your shoulders down and avoiding excessive arching of the back. This helps to prevent injury and maximize the effectiveness of the exercise.
