Excessive Quantity or Depth: What Builds Extra Muscle? – Greater Stronger Leaner – COMMUNITY

It Relies on Your Expertise Degree

Coaching forces you to evolve as a lifter. What works finest for it’s best to evolve as nicely. Right here’s why.

One of many massive debates in energy coaching is whether or not or not maximal good points are made with low or excessive quantity. It’s an insanely frequent debate. It’s additionally an insanely pointless debate! Neither one is healthier or worse, typically talking.

See, program design isn’t one-size-fits-all. So, no one can actually win this battle. The argument results in 1,000,000 totally different context-specific eventualities the place both one may be higher than the opposite. There’s even analysis to assist every one being higher than the opposite. That’s why we have now camps on each side, stuffed with lifters, coaches, and even researchers.

Nonetheless, by the tip of this text, you’ll perceive every part it’s essential find out about quantity and depth so you may ignore those that don’t know what they’re speaking about and really practice with the right doses wanted for optimum good points.

Let’s Outline Quantity and Depth

For those who’re like most lifters, you in all probability thought (or nonetheless suppose) that depth means how exhausting you’re going. However we’re referring to how the literature defines it.

Depth, outlined by the evidence-based energy coaching group, refers back to the load you employ. So, a high-intensity program is one which makes use of greater masses with decrease reps. That is your traditional Wendler 5/3/1 kind of program.

Quantity, outlined by the identical evidence-based crowd, refers back to the complete quantity of labor you’re doing. This generally is a bit extra complicated as a result of there are two alternative ways to have a look at it. Right here, we’ll solely give attention to one (which is extra generally used when referring to maximizing hypertrophy).

Initially, quantity meant your complete tonnage, and it’s usually nonetheless used this fashion in powerlifting circles. Right here’s a basic math equation to interrupt it down:

Load x Reps x Units = Whole Quantity

The newer and extra frequent definition for quantity, which we’ll give attention to right here, is by your complete units. Particularly, when counting quantity this fashion, we’re speaking in regards to the complete quantity of weekly units carried out per muscle group:

Whole Units Per Muscle, Per Week

What Does Analysis Say?

The reality is that the majority analysis factors to greater quantities of quantity being extra favorable for muscle development. This has been such a sizzling matter over the past a number of years that there’s an impressive quantity of analysis pointing within the path of upper volumes being higher for development.

We’ve a pair research displaying higher muscle development with decrease volumes, too, and the frequent rationalization there may be that with greater volumes being carried out, cortisol (the catabolic stress hormone) is elevated extra usually. That would doubtlessly restrict the quantity of development seen.

It is a sound argument as a result of cortisol is a catabolic (breakdown) hormone that causes muscle loss in some eventualities. Additionally, cortisol may be the catalyst to different downstream destructive results, hormonally talking – chronically elevated cortisol inflicting T3-T4 (thyroid) conversion, inflicting points together with your metabolism, and even inflicting decrease testosterone ranges.

Nonetheless, that on-paper-theory doesn’t all the time maintain its weight.

For instance, there’s analysis displaying a correlation between elevated cortisol ranges and better testosterone ranges in males. Why is that? It’s easy: coaching exhausting elevates cortisol! That’s a sympathetic nervous system response that kicks you into a better state of efficiency, inflicting you to carry heavier and with extra reps. That, you guessed it, builds extra muscle and afterward produces much more testosterone.

So we are able to’t depend on something short-lived right here, and until you’re in a state of chronically elevated cortisol, you received’t be seeing any destructive results from cortisol developing each occasionally.

Now, again to the analysis on high-volume coaching…

Numerous research show that higher-volume coaching packages construct extra muscle than lower-volume coaching packages. We even have some newer analysis displaying particular proportion will increase boosting hypertrophy. (One cool research elevated a lifter’s present quantity to see what number of extra units had been wanted to construct extra muscle.)

What Do Seasoned Energy Coaches Say?

What in regards to the previous meatheads in these dirty gyms which have been lifting for many years and getting themselves and their shoppers completely jacked? These are your traditional powerlifting guys who love lifting heavy, utilizing chains, smelling salts, and lifting in gyms with rats within the corners.

And earlier than you assume I’m a lab coat man who simply does curls on the native Planet Health, I spent the primary decade of my profession in a type of gyms. Actually, I now personal a personal fitness center with weight releasers, platforms, chains, and each specialty bar you may consider. However what I’m not is a dogmatic coach who believes that what works finest for me will work finest for you – and that’s precisely why you may’t all the time hearken to the previous guys.

See, they consider low quantity works nicely as a result of they like to carry heavy weights with compound lifts. Their argument is that compound lifts hit extra muscle teams, which is true, and that lifting heavier creates a better quantity of complete stress, which can also be true. There are issues right here, although.

First, by hitting extra muscle teams with one carry, you’re additionally isolating much less and offering much less quantity to every muscle. It’s additionally extraordinarily taxing, neurologically, which doesn’t all the time help you make that quantity up.

Second, you may not be robust sufficient to create sufficient complete stress… but! For those who’re nonetheless solely benching 185 kilos for 8 and the man providing you with this recommendation is benching 315 kilos for 8, nicely, do the mathematics. His complete tonnage is much larger than yours. That makes his complete quantity, and subsequently his muscle mass, larger than yours as nicely.

Some extra arguments right here, although, maintain their weight: the facets of energy being simpler to trace progressive overload with, motor-unit recruitment being larger with heavier masses, and, final however not least, heavier masses stimulate extra fast-twitch fibers.

All of that is true, too, though we all know that fast-twitch fibers are additionally stimulated by reaching a excessive stage of fatigue or proximity to failure. So it’s not the load that stimulates the fibers; it’s that it’s simpler to stimulate them with heavier masses attributable to reaching failure sooner inside a set, in comparison with lighter masses with greater reps.

Expertise Degree: What It All Comes Down To

Now we all know why the 2 camps every declare that they’ve the most effective path to maximizing muscle development. And that is the place I nail you with the reality of the matter: the quantity of quantity you want, and depth you need to be coaching with, is based in your expertise stage within the fitness center. Try this graph:

On the left y-axis (vertical), we have now quantity. On the x-axis (horizontal), we have now expertise stage. The pink inverted-u curve represents quantity wants as you acquire extra lifting expertise.


First, everyone knows the saying, “Something works whenever you’re a beginner.” That’s true. It’s why it’s best to all the time begin with much less quantity, since you’ll expertise extra muscle injury, and with much less quantity, you may prioritize getting stronger and extra expert at lifting. Your talent acquisition and neuromuscular capabilities are fairly crappy at this level, and it’s essential spend time there. So that you begin on the decrease finish of the evidence-based quantity vary, which is 10 units per muscle per week.


Subsequent we have now the intermediate lifters who can now deal with plenty of quantity. These individuals are the first contributors within the analysis research talked about above and get plenty of development from pushing the quantity ceiling as excessive as attainable whereas nonetheless recovering. Primarily based on the evidence-based suggestions for muscle development, this shall be at about 20 units per muscle per week.

Superior Lifters

And eventually, we have now the superior and seasoned lifter who has spent years and years within the fitness center. This individual has an excellent talent stage with lifting and might fireplace muscular tissues maximally. Their nervous system is primed for heavy lifting, and so they seemingly have taken a beating over time from lifting a lot. They need to begin to taper their quantity again all the way down to 10 units, just like the beginner.

Now, as exhausting as that’s for some to consider, it’s the rattling reality. The actually superior lifter creates extra mechanical stress in each rep, which suggests she or he will get extra out of every rep! But additionally, it makes each rep extra fatiguing as a result of they will produce extra drive, and their stage of energy – being a lot larger than a beginner – causes way more neurological fatigue and stress on their joints.

However that’s not all. These superior lifters have gotten far nearer to their very own genetic ceiling than the beginner or intermediate lifter. This implies they not solely want much less quantity (through units) to provide as a lot complete quantity (through tonnage) because the youthful lifters, however additionally they have much less reward to achieve from the danger.

Placing This Into Follow

Right here’s what it’s essential take away to get probably the most out of your program:

The quantity of quantity you want is extra tied to your expertise stage within the fitness center than anything.

So, if you happen to’re in yr one or two of lifting, don’t hearken to the man who’s in yr 10 until he’s telling you what he did again when he was on the identical stage as you.

As you spend extra time within the fitness center, you may attain greater quantities of quantity and get plenty of muscle development out of it. Analysis helps this through the use of contributors who’re skilled lifters relatively than newbies, however very not often have they got seasoned energy coaches or bodybuilders as research contributors.

When you get so robust and proficient at lifting weights that your greater quantity classes start to actually tax your physique and full system, it’s time to pump down the quantity. This normally occurs past yr 5, however usually extra so round yr 10.

Over your lifting profession, it’s finest to remain inside the vary of 10 to twenty units per muscle per week. For those who’re already a long time into it, you could possibly look again and see that you just, too, went from round 10 to twenty to 10 units per muscle per week. You probably did it naturally with out fascinated by it.

Lastly, there are outliers right here as nicely. A professional-bodybuilder should use excessive quantity with lighter masses when he’s in yr 20 of his profession. However it is because his sport requires way more isolation workout routines, and it’s simply plain silly to do curls for units of 3-5. Likewise, a aggressive powerlifter is on the other spectrum as a result of he additionally follows the ideas of specificity.

So, on the finish of the day, concentrate on what your coaching is like, how excessive your aim is, what the calls for are, and the way you’re feeling when doing both route. That means, you may work out what works finest for you.
