When it comes to maximizing muscle growth, one of the most debated topics in the fitness world is training volume—how many sets per muscle group per week you should be doing. While some lifters swear by low-volume, high-intensity routines, others advocate for pushing volume as high as possible to keep gains coming. So what does the research actually say? And how can you apply it to your own training?
Let’s break it down with evidence-backed insights and real-world recommendations for hypertrophyLet’s break it down with evidence-backed insights and real-world recommendations for hypertrophy
Understanding Training Volume: The Basics
In simple terms, training volume refers to the total number of sets performed for a specific muscle group within a given week. For example, if you do 4 sets of chest presses on Monday and 6 sets of incline dumbbell presses on Thursday, that’s 10 weekly sets for your chest.
Most fitness experts and researchers agree that weekly volume is one of the primary drivers of muscle hypertrophy. But the optimal range can vary depending on training experience, recovery ability, exercise selection, and individual goals.
The 10 to 20 Set Guideline: A Practical Starting Point
A widely accepted recommendation is to aim for 10 to 20 working sets per muscle group per week. This range isn’t arbitrary—it’s supported by a 2017 meta-analysis conducted by Dr. Brad Schoenfeld, Dan Ogborn, and James Krieger, which concluded that performing more than 10 sets per week significantly outperformed lower volumes in terms of muscle growth.
That said, 10 to 20 sets is not a hard rule. It’s a reasonable guideline—especially for intermediate lifters—providing a balance between stimulus and recovery. Below 10 sets, you might not be doing enough to trigger growth. Above 20 sets, you risk diminishing returns, or worse, entering a state of overtraining if recovery isn’t dialed in.
Diminishing Returns and Potential Drawbacks of High Volume
It’s important to recognize that while more volume can yield greater results, the benefits tend to taper off the higher you go. At some point, adding more sets leads to less additional muscle gain per unit of effort—and may even hurt recovery, increase fatigue, or raise your injury risk.
For instance, jumping from 10 to 20 weekly sets might give you a solid boost in muscle growth. But going from 20 to 30 sets? That boost becomes smaller—and your need for rest, nutrition, and sleep increases dramatically. Beyond 30 sets, most lifters will struggle to recover unless they are genetically gifted, highly advanced, or taking performance-enhancing drugs.
Is There Actually an Upper Limit to Volume?
Interestingly, some newer research challenges the idea that volume must eventually backfire. In recent discussions led by James Krieger and others, data suggests that some individuals continue gaining muscle even at 30+ sets per week, without showing clear signs of overtraining.
However, this doesn’t mean everyone should go out and start hammering 30 sets per body part every week. As with most things in fitness, context matters. Training history, exercise selection, age, sleep, and nutrition all play a role in how much volume you can tolerate.
Also, most studies haven’t demonstrated actual muscle loss from high volume, just that gains tend to plateau. That means even if you don’t regress, you might just be wasting time doing excessive work with minimal payoff.
Quality Over Quantity: Not All Sets Are Created Equal
A major oversight in volume discussions is the assumption that all sets are equally taxing. In reality, a set of heavy Romanian deadlifts is far more demanding than a set of seated leg extensions. Compound, free-weight movements generally create more muscle damage and require more recovery than isolation exercises or machine-based work.
Therefore, volume must be considered within the context of exercise intensity and movement type. Ten sets of squats and deadlifts is not the same as ten sets of cable curls. Smart programming accounts for this and balances heavy, taxing lifts with lighter, easier-to-recover-from work.
Specialization Phases: A Strategic Way to Use High Volume
If you’re looking to bring up a lagging body part, one effective strategy is to run a specialization phase. This involves dramatically increasing volume for one muscle group—potentially up to 25 or 30 weekly sets—while reducing volume elsewhere to maintenance levels (about 8–12 sets).
For example, if your arms are a weak point, you might increase biceps and triceps volume while keeping chest, shoulders, and legs at the low end of the volume range. You’d run this for 4 to 6 weeks, then rotate to another body part, allowing the high-volume area time to recover.
This approach lets you apply high volume intelligently, without overwhelming your whole system.
Monitoring Progress and Adjusting Volume Accordingly
The most important takeaway is that volume is not one-size-fits-all. If you’re gaining strength, building muscle, and recovering well, your current volume is probably sufficient. If you’ve stalled in progress and feel fresh, it may be time to bump volume up by 10–20%.
On the flip side, if you’re always sore, fatigued, or getting injured, it’s a red flag that you might be doing too much—and reducing volume could actually help you grow more efficiently.
Listen to your body, track your performance, and be willing to adjust as needed.
Final Thoughts: Volume Is a Tool, Not a Goal
Rather than obsessing over hitting a magic number of sets, treat volume as one of several variables that you can manipulate to keep progressing. It works best when combined with proper intensity, technique, nutrition, and recovery.
Yes, 10–20 sets per muscle group per week is a solid baseline for most people. But whether you lean toward the lower end or experiment with the higher end depends on your goals, experience, and recovery capabilities.
And most importantly—remember that more isn’t always better. Sometimes, the key to unlocking gains is doing just enough, not as much as possible.
