How to Gain Weight and Build Muscleby Mark Sisson

So you wanna put on some lean muscle mass. And you want to do it within the context of the Primal Blueprint, but aren’t sure where to start. It’s a common question and it’s about time I addressed it head on.

As I’ve made pretty clear, our ultimate goal is to achieve positive gene expression, functional strength, optimum health, and extended longevity. In other words: To make the most out of the particular gene set you inherited. These are my end goals, and I’ve modeled the PB Laws with them in mind. But that doesn’t mean packing on extra muscle can’t happen with additional input. After I retired from a life of chronic cardio and started living Primally, I added 15 pounds of muscle, while keeping low body fat levels without really trying, so it’s absolutely possible for a hardgainer to gain some. The question is how much and at what expense?

I’d be the first to tell you that lean body mass is healthier than adipose tissue. Generally, the more lean mass a person has, the longer and better they live. But to increase mass at the expense of agility, strength, or speed is, in my opinion, counterproductive. What would Grok do – go for enormous biceps or the ability to haul a carcass back to camp? Unless you’re a bodybuilder (nothing wrong with that, mind you; it’s just not my focus), I can’t advise simply packing on size without a proportional increase in actual strength. Those bulging biceps might look good on the beach, but then again, so does the body that comes with keeping up with the younger guys, knocking out twenty pull-ups in a row, and lifting twice your bodyweight. Form is best paired with a healthy serving of function. The two are quite delicious together, and, luckily, following the PB allows us to get both without sacrificing either.

Of course, we’re all built a little differently. The basic building blocks are the same in everyone, but sexual reproduction (as opposed to asexual reproduction) has the funny habit of producing unique genetics and small variations that affect the way we respond to our environments. It’s why some people are short and some are tall, or why some of us respond better to carbohydrates than others. Even though we all pretty much operate the same way, there IS a range of possible outcomes that is proscribed by your direct ancestors. By that same token, some people just naturally have more muscle mass. They’re usually innately more muscular than the average person, and putting more on through resistance training is often an easy task. Then there are those who can’t seem to gain a pound: the hardgainers. They might be increasing strength, but it doesn’t seem to translate into visible muscle mass. Now, my initial advice for a hardgainer is this – don’t worry too much about it! As long as you’re getting stronger, you’re doing it right.

Let’s face it, though. You’ve probably heard that enough already. It’s fun being the lanky guy at the gym who can lift more than most, but you’re dead set on bulking up (who doesn’t like a bit more muscle to go along with that strength?), and you want to do it in a Primal context. Besides, continuing to increase strength will eventually require increasing size. To do so, you have to target the very same anabolic hormones that others use to get big, only with even more enthusiasm and drive. Like I said, we all have similar engines, but some require more fuel and more efficient driving (sorry for the corny analogy). Activating these hormones will work for anyone, provided they work hard and eat enough food.

The main hormones that contribute to muscle anabolism are testosterone, growth hormone (GH), and insulin-like growth factor-1 (IGF-1). A little more about each and how to utilize them:

Testosterone

Crazy bodybuilders don’t inject themselves with anabolic steroid hormones that are based on testosterone for nothing. Among other roles, testosterone is an important muscle-building growth factor that favorably affects protein synthesis in addition to working with other hormones (like GH and IGF-1) to improve their function (more on this later). If you want to increase strength and build muscle, testosterone is absolutely required (don’t worry, though: no injections necessary!).

Growth Hormone

It’s right there in the name, isn’t it? Growth hormone. It helps muscle grow and, perhaps more importantly, it burns body fat. After all, leaning out is a big part of building muscle (or else you’ll just look puffy) and GH will help you do it.

Insulin-like Growth Factor 1

IGF-1 is extremely similar in effect to GH, as it should be – GH stimulates IGF-1 production in the liver. In fact, it’s suspected that IGF-1 is actually responsible for most of the “growth-promoting effects of circulating GH.”

Anabolic hormones all work together. In fact, to maximize their muscle-building potential, you must have all three present. Testosterone increases IGF-1, but only in the presence of GH. GH promotes skeletal muscle cell fusion independent of IGF-1, but the two are most effective in concert. Luckily for you, the types of exercises that stimulate the secretion of one will generally stimulate the secretion of the others. Funny how that works out, huh?

Enter The Central Nervous System

In order for your body to start pumping out these delicious anabolic hormones, you must first give it a reason to do so. I might even say you should give your genes a reason to express themselves. The most effective way to do this is by notifying the central nervous system. Now, the CNS can be a stubborn bastard, but he’s all you got when it comes to interpreting stimuli and relaying messages to the rest of the body. He’s not easily perturbed, and he won’t bother if you aren’t serious. If you insist on doing nothing but light aerobics or tiny isolation exercises, your CNS will barely notice. If you want to get your CNS’ attention, pick up the intensity. Run some sprints or do some heavy lifting. When you do an exercise like the squat with a heavy weight, all hands are on deck. Your CNS realizes that some serious exercising is going down and notifies the hypothalamus, which in turn talks to your pituitary gland. This tiny – but vital – member of the endocrine system is the gland that dispatches luteinizing hormones to tell the testicles to secrete testosterone. It’s also the gland that synthesizes and secretes GH. IGF-1 is mostly produced by the liver, but its production is facilitated by the presence of GH, so we can see that it all comes down to CNS stimulation. Chronic cardio doesn’t affect your CNS in any meaningful way, so that’s why we tend to avoid it; vigorous sprints, hard and heavy lifting, and anaerobic output will get its attention, so do plenty of these to maximize muscle growth.

Cortisol: A Hormone to Avoid

Promoting muscle and strength growth also requires avoiding excess amounts of catabolic (muscle wasting) hormones like cortisol. Cortisol is the major stress hormone, and it exists for a very legitimate reason (dealing with “flight or fight” incidents, inadequate sleep, anxiety), but in large amounts cortisol increases serum amino acids by breaking down muscle, inhibiting protein synthesis and reducing amino acid uptake by the muscles – all awful things for muscle growth. Compounding the problem even further, the broken-down muscle is converted into blood glucose, which then raises insulin secretion and increases insulin resistance while promoting fat storage. And we all know how great those muscles look with a nice layer of adipose tissue covering them up! On a serious note, most people following the PB already minimize cortisol by getting plenty of sleep and reducing stress, but if you’re preoccupied with building muscle mass and engaging in extended workout sessions to achieve it, avoiding excess cortisol can get tricky: excessive exercise without enough recovery time actually increases cortisol. It makes sense (think of it like your body’s telling you it needs a day or two off), but the desire for more muscle mass drives many to work out to the point of counter-productivity. Just be careful, and give yourself at least a day of rest after a particularly grueling session.

Lift Really Heavy Things

If you haven’t figured it out already, you’re going to be doing some heavy lifting in order to put on lean mass. The foundation of your routine should be the big compound lifts: squats, deadlifts, presses (bench and overhead), pull-ups, rows, dips, snatches, power cleans, clean and jerks. These engage multiple muscles while triggering your hormonal response systems. Bodyweight stuff, while valuable, simply isn’t going to get you the strength and mass increases you’re looking for. Testosterone, while useful, only gets really anabolic when you start lifting. You need to get under some decent weight, enough so that your CNS and endocrine system are blasted, but not so much that you can’t maintain proper form.

A popular routine is the 5×5 method. Popularized by programs like StrongLifts and Starting Strength, doing compound lifts for five sets of five reps allows you to strike a balance between strength building and superficial muscle hypertrophy. Done this way, your hypertrophy won’t be purely sarcoplasmic, which results in fluid-filled muscles that look big but don’t see a corresponding increase in actual strength. Instead, the 5×5 method promotes myofibrillar hypertrophy: hard, dense muscle fibers that increase strength and size (with no puffiness). That’s real muscle that would make Grok proud.

If you’re lifting heavy and lifting hard, keep your workouts spaced at least a day apart and don’t lift more than 3x/week. Three exercises per session should be perfect. That may not sound like much, but it’ll be plenty if you do it right. Remember, you’re doing big compound movements that will really shock your system, with an emphasis on intensity and power. You don’t want to overwork yourself, release a bunch of cortisol, and set yourself back a few weeks.

Squats and deadlifts are absolutely required. No excuses. They engage the most muscles and produce the biggest hormonal response. They will be the bedrock of your mass building campaign. Most programs recommend doing squats every session, and I tend to agree. You can handle it. Deadlifts are a bit more taxing and so should be relegated to every other workout. So, one week you’ll deadlift once, the next week twice. You can also sub in power cleans for the occasional deadlifts (or do them in addition) if you’re comfortable with such a complex movement. Presses are paramount, both overhead and bench. I’d alternate both types of presses every session. Pull-ups are great, but weighted pull-ups are even better. Same goes for dips. Just try to get one pulling, one pushing, and one squatting exercise in each session.

An example for beginners, with sets coming first in the sequence:

A
Squat 5×5
Pull-ups 5xFailure (add weight if “Failure” is becoming more than 12 reps)
Overhead Press 5×5

B
Squat 5×5
Deadlift 1/2/3×5 (your choice; deadlifts can be incredibly taxing, and with exhaustion comes poor form, so be careful; sometimes it’s better to do a really heavy load for a single set)
Bench Press 5×5

C
Squat 5×5
Pull-ups 5xFailure
Overhead Press 5×5

Do this sequence every week (maybe Monday, Wednesday, Friday) and steadily increase the weight each session. Once you’re making progress, feel free to add in other exercises like dips or more Olympic lifts. For more mass, more lactic “burn” (and more GH secretion), reduce your rest periods between sets or even superset them. If you feel like doing some cardio, stick to sprints once weekly, or even a Crossfit-style metcon (metabolic conditioning) workout, maybe some Tabata burpees. The key is conserving strength and giving your body time to rest and recover for the next round of squats, deadlifts, and presses.

This “program” can be tweaked and altered. Just make sure you’re doing big movements while maintaining extreme intensity and great form. Oh, and always make sure to squat and deadlift. Always. They produce the most testosterone, GH, and IGF-1.

Eat Lots (I Mean Lots) of Plants and Animals

No one would ever call the Primal Blueprint a protein-sparing plan, but you’re going to have to eat even more than before. Stuff yourself. I always say that body composition is 80% diet, and that goes for putting on mass as well as losing fat. You need to provide plenty of protein for all those hormones to synthesize, after all.

• Never let your protein intake go lower than 1g/lb of body weight when you are aiming to add long-term muscle. It’s the building block of muscle, and your body is going to be starving for it.
• Eat plenty of saturated and monounsaturated fat. Fat blunts insulin secretion while increasing testosterone production. Insulin may be useful for stuffing your muscles full of glycogen, but that’s not what you’re going for… right?
• Dietary fat, in conjunction with all the GH you’ll be producing, also spares muscle wasting.
• You may have heard of the popular GOMAD method – Gallon of Milk a Day for easy mass-building. It undoubtedly works, but a gallon of milk isn’t exactly Primal and I can’t recommend it. Instead of milk, why not a dozen eggs a day? ADEAD? If you can manage it, eating them on top of your regularly scheduled meals is a great source of affordable protein, fat, and vitamins (Vitamin A in particular may have pro-anabolic effects).
• Eat often. If you’re going for pure size and strength, fasted workouts and skipped PWO meals may not be the ticket. You’ll burn more fat with the extra GH secretion and existing muscle will be spared, but you may be missing the chance at prime protein synthesis when you fast. A PWO meal of protein and fat will still blunt the insulin secretion and provide fuel for your muscles.
• Increase caloric intake. You’re going to be expending so much energy on the lifts (and you’ll continue to burn through it even on rest days) while eating clean, Primal foods (and keeping insulin low as ever) that fat accumulation shouldn’t be an issue at all. Eat!
• On those days when you do expend a ton of energy – maybe on your metcon or sprint day – having a Primal-friendly starch, like squash or sweet potato, is a decent way to replenish depleted glycogen stores.
• Eat a big piece of fatty meat every single day. Steak, whole chicken, lamb leg, organs, whatever. Just eat a solid piece of animal flesh for a powerful protein infusion on a daily basis.
• A hardgainer is often someone who doesn’t eat enough. Sure, genes play a role, but you can ultimately have a significant say in how those genes rebuild you. To a point. Eat more and lift harder to grab the reins.

I’m a firm believer in the body’s natural ability to achieve proper homeostasis, provided we supply the right environment and the right foods. For some of you, that might mean lower body mass, lower than you’d like. In my opinion, that amount of muscle is probably “right” for you and I wouldn’t recommend going above and beyond to achieve more of it… but I also wouldn’t condemn it, especially if it’s pursued in accordance with the Primal Laws. As for me, I am comfortable where I’m at and tend not to seek added mass (I’m also at a point where lifting heavy increases my risk of injury, and I HATE downtime). But if you are a hard-gainer looking to add a few, as long as it’s not just show muscle and you can actually lift some decent weight and at the very least manipulate your own body weight comfortably, eat those dozen eggs and gain that weight.
