Give your body the best chance at building muscle mass by exercising to your ultimate level of fatigue. Make sure that when you stop, you truly are not capable of doing even one more repetition. This will most effectively break your muscles down, causing your body to work harder to build them back up again, and leading to the ripped muscles that you are looking for.
If you have enough time, consider breaking up workouts into two different sessions per day. For example, you could train your chest in the morning, and then once evening strikes, you can train your back. Resting your body in between lets your energy stores recover better than training both muscles during the same workout.
In order to build muscle it is important for you to properly fuel your body. Drinking a protein shake that is loaded with essential vitamins is a great way to give your body the nutrients it needs to repair torn muscle fibers and ultimately build the larger muscles you want.
