Cable flies are a strength training exercise primarily targeting the pectoralis major muscles in the chest. This movement is performed using a cable machine, which allows for constant tension throughout the exercise. To perform cable flies, you 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. This exercise helps improve chest definition and strength, making it popular among fitness enthusiasts. Cable flies can also engage the deltoids and triceps, providing a comprehensive upper body workout. Proper form is essential to avoid injury and maximize effectiveness.
