Developing massive pectorals is simply a matter of performing the proper amount of sets, repetitions, and targeting all the angles of the chest. Knowing the answer to these three points will allow you to then create the best chest workout for mass that suites you. The number of sets you perform are crucial when building mass to ensure that you are not overtraining the muscle. Repetitions play a big role in the type of muscle hypertrophy you trigger. This will determine whether you actually pack on size or simply increase strength and density. Lastly, making sure that you target every part of the chest will allow you to get a larger and more developed pectoral muscle.

Sets: When building a massive chest, 3-4 sets is more than enough. Although the chest is a larger muscle, each angle is only a very small portion of that. Focusing too much on one part of the chest can easily result in overtraining. When targeting each section of the pectorals, 3-4 sets is a sufficient amount in order to put enough strain on the that part of the chest to cause muscle growth(assuming you are performing the correct amount of repetitions).

Repetitions: When you are performing your “best chest workout for mass”, you must first understand that your main goal is size. In order to build size on a particular muscle group you must trigger sarcoplasmic hypertrophy. Contrary to popular belief, muscle cell size is actually created by lighter weight with high repetitions. Fatiguing the muscle with 12-15 repetitions will cause the muscle cell to grow larger. The rep tempo should be quick with no pause while keeping proper form. Your eccentric movement should be about 1 second, no pause, and your lift should be another second (1-0-1). If you are able to perform more than 15 repetitions, increase the weight a bit. If you are unable to perform at least 12 reps, decrease the weight. Due to the fact that fatiguing the muscle is the main focus, make sure to keep your rests short (30-45 seconds in between each set).

Be sure to keep proper form while lifting at this rep tempo to avoid injury.
