Another exercise that will help you on how to get bigger chest is the Cable Crossover. This exercise is somewhat similar to the dumbbell flys. It targets the inner chest and also works to bring out the impressive striations in your chest muscle. From a standing position, hold the cable handles attached to the overhead pulleys.
Bend your upper body slightly forward, with arms extended out on the sides, but keep your arms slightly bent. Bring your arms and hands together toward the center of your body as if you're hugging someone. Make sure your arms crossed each other.
