Gaining Mass with P90X®
By Steve Edwards"Don't want to look small!" —Lou Ferrigno in Pumping Iron
Guys have a thing for mass. It's hard to explain, really, but boys seem to grow up wanting nothing more than to be big. Guys want speedboats and trucks, and they want to look like the Hulk®, regardless of what their wives may think of green skin. If this sounds like you, here's the article you've been looking for: customizing P90X for mass.
Even if mass is your only goal, make sure to read the other articles in the series on customizing the X. (See Related Articles at the end of this article.) The principles discussed in these articles will be put to use here. To look like the Hulk, you don't need to be a physicist who's accidentally exposed to gamma rays, but you do need to consider science as we know it, particularly the question, "What is mass?"
What is mass?
Because many of our Success Stories, not to mention Tony, aren't exactly skinny, we must begin by defining mass—something most of you are looking for more of. Physics-related talk about inertia, gravity, and force aside, as we're using the term here, mass simply means size. As in the root of the word massive. A program targeting mass is concerned with one thing: muscle growth (from here on in referred to as hypertrophy), and a lot of it.
In a training cycle for mass, we should target hypertrophy even at the expense of other fitness goals. P90X is not a system designed for mass. It's designed for overall fitness, which means that ultimate gains in targeted areas, like speed, strength, flexibility, and muscle growth, are compromised to provide a program that improves all your body's physical energy systems during one 90-day effort. We feel that this is the preferred training system, because it addresses the big picture. But if your picture is quite literally being bigger, you'll need to read on.
Foundation
You've read about the capacity for improvement throughout this series, so here's where I tell you to do a round of P90X as it's designed before embarking on a mass-specific program. It's healthier, sure, but it's more than that. Training all of your body's energy systems until they're running efficiently increases your body's ability to do, well, anything. And "anything" includes looking like Lou Ferrigno. Once you've done a round of the X and aced your Fit Test, the foundation has been laid. You're ready to start gettin' big.

The difference between size and strength

Periodization
The periodizational concepts that have been discussed in previous articles need to be explained here before a mass schedule is created. Remember that a standard schedule would look similar to this:
Foundation phase (Power 90® or what you did pre-X) + block 1 + transition/recovery + block 2 + transition/recovery + block 3 + recovery = peak (final Fit Test)
The difference here is that we're going to structure an entire training cycle based only on hypertrophy. This means we won't be setting up a peak phase. Over a long period of time, you'll want to teach your muscles how to function more efficiently. We'll get to this at the end.
For now, we'll just say that there's still a periodizational approach to consider. You'll still adapt, gain, and plateau over time, so we'll need a structure to keep this happening. But the structure will be dependent simply on rep schemes (the number of repetitions that you target to bring you to failure) and progressive overload. The blocks of our 90-day schedule will each target a different number of repetitions, which you'll want to aim for to induce failure. But because we're not changing the schedule much, and thus creating less Muscle Confusion™, we won't need such frequent recovery phases.
Progressive overload
Hypertrophy is all about creating progressive overload. To create muscle growth, you must keep stimulating the muscles during each workout. This requires that you add weight as necessary to create failure at similar points in time. (We use reps as a reference point but the actual measure is force over a given amount of time.)
Recovery
The more we can focus on hypertrophy, the more muscle we'll gain. Since we only have so much energy to expend, this means we should spend less time working on other areas. This is where you'll see the biggest differences from the traditional P90X schedules. When you're not training for hypertrophy, your entire focus should be on preparing your body to create more hypertrophy. Therefore, the P90X mass schedule will have a lot of active recovery and flexibility work and very little intense cardio. This means we'll spend more time recovering during each training block and taking fewer periods focused solely on recovery.
Putting it all together
Before we get to the schedule, here are some general things to consider. The first is pacing. Instead of following the kids in the videos, target your rep scheme (and push pause when necessary). Do each set to failure, or as close as you can get, without exceeding your targeted number of reps by more than a couple. If you lack enough weight to induce failure, try slowing down the movements so that you're holding your contraction long enough that you're fighting the pump. The force over time equation only works if you're pumped silly. With this in mind, do not use the pause button simply to increase the time between exercises. You want to be pumped through the entire workout. No pump = no growth.
A good way to choose the resistance for each movement is to use enough so that you can only do the lower number of your targeted rep scheme. Once you can do the higher number, it's time to increase the resistance.
Do your repetitions slowly and with control. Speed is for power, not size. Focus on perfect form and only add weight when you can do each rep with great form.
When you're done, you're done. You don't need to finish an entire workout if you're struggling. Once you lose the ability to move the weight or do the move in strict form, stop the workout. Any further training would only create more breakdown than you could recover from and increase your risk of injury.

Final note: This is an entire cycle of training based only on hypertrophy. To have an athletically efficient physique, you should do other training cycles that target different goals. Even if your only goal is hypertrophy, training these other systems properly will improve your body's physical systems and increase your capacity for muscle growth, as well as the speed at which you can add or shed muscle and fat. So while you can tweak and reuse this basic structure over and over, it will also benefit you to get back to basics and do P90X Classic from time to time.

P90X, on the other hand, is designed with a different purpose. The nutrition plan is designed to help you change your body composition, not just just lose weight. Which means you will be eating to build muscle, not just lose fat. It's designed with a heavy dose of resistance training, again so that you build muscle, not just lose fat.
