Just as with all the other major muscles in your body, if you want to increase the size and strength of your chest, you need to work it from a variety of angles using a mixture of exercises.
The bench press is a compound move that works the shoulders and the triceps as well as the chest, while the cable cross-over is an isolation move that will directly target the chest muscles. It’s an exercise favoured by bodybuilders because it does wonders for the definition of your chest muscles.
