Incorporate compound movements into the beginning of your workout to stimulate the highest number of muscle fibers as well as release the maximum amount of testosterone and growth hormone.
If you are constantly in your comfort zone your body will never progress, incorporating maximum intensity lifts is essential to muscle growth as it shocks the muscle and forces growth.
While certain areas of the chest simply cannot be isolated, they can be focused on. Be sure to work at various inclines ranging from decline to 45 degrees.
You’ll get a better range of motion and force the muscle to work harder using dumbbells as opposed to a barbell.
Once you’ve finished all of your compound lifts and key movements, finish up with isolation movements such as flies or cross overs. Isolation movements are essential to your workout as they allow you to really focus your efforts on key areas. Work with lighter weights and higher reps for your isolation exercises.
