Does more training build more muscle? Only up to a point, and for the hard gainer that point comes early. Growth = stimulus × recovery, not sets × ego. Beyond a certain point the effect flips: more volume produces more fatigue, but not more muscle growth.

The Myth
“More training = more muscle.”
“If I train twice as much, I’ll grow twice as fast.” Sounds logical, but it’s wrong. Linear thinking transfers a principle from the workplace onto physiology: more input, more output. On the body, this only holds up to a point.
Beyond that point the effect flips: more becomes less. Recovery stalls, performance plateaus, injury risk rises, and the hardgainer wonders why nothing is happening despite maximum effort.
Why the Myth Persists
“No Pain, No Gain” is the most repeated mantra in training, and the most widely misunderstood. It originally describes the necessity of discomfort and effort, not endless set counts. The phrase gets conflated with volume: more sets = more pain = more results. That’s a false chain.
Then there’s the beginner bias: in the first months of training the body is so unadapted that almost anything works, including high volume. When this pattern is carried into more advanced training, it tips into overtraining.
Social media amplifies the picture further: what gets shown are extended workouts, packed daily schedules, six training days a week. What doesn’t get shown: professional recovery infrastructure, dialled-in nutrition, sleep optimisation, or simply genetic outliers.
For a hardgainer with an already limited recovery capacity, excessive volume is particularly counterproductive.
The Facts: Volume, MEV and the SRA Curve
Muscle growth follows the SRA curve: apply a stimulus, recover, then adapt. Constantly applying stimuli without recovery prevents adaptation entirely.
What the research shows:
| Range | Sets/muscle/week | Effect |
|---|---|---|
| MEV (Minimum Effective Volume) | ~4 to 8 | Growth begins, fatigue low |
| Optimal volume | ~10 to 16 | Maximum stimulus at manageable fatigue |
| Junk volume | >20 (hardgainers) | Fatigue > adaptation, counterproductive |
Stimulus-to-Fatigue Ratio
Every training set produces two things simultaneously: a growth stimulus and fatigue. At low volume, the stimulus dominates. Beyond the junk volume threshold, fatigue accumulates faster than the stimulus, the net balance turns negative.
RIR and RPE: Intensity Beats Volume
RIR 0 to 2 (0 to 2 reps in reserve) per working set is sufficient to mechanically overload the muscle. Someone training at RPE 6 to 7 across 25 sets achieves less than someone training at RPE 8 to 9 across 12 sets.
Example: Hardgainer, Chest, 20 Sets/Week
A hardgainer trains chest with 20 sets per week. Result after 4 weeks: stalling strength, disrupted sleep, shoulder discomfort. The body is no longer fully recovering between sessions, a classic sign of overreaching.
Adjusting to 10 to 12 quality hard sets with RIR 1 to 2, focus on technique and controlled progressive overload: strength climbs, recovery improves, muscles grow again.
Mechanisms: Why Less Is Often More
1. The SRA Curve
The SRA curve describes three phases following a training stimulus: stimulus (the training session), recovery (return to baseline) and adaptation (supercompensation above baseline).
Training before the recovery phase is complete means the next stimulus lands on a weakened system. After several such cycles, fatigue accumulates, performance and muscle growth stagnate or decline. This is the physiological mechanism behind overtraining.
2. Deload as a Growth Tool
A deload, a deliberately reduced training week (60 to 70 % of normal volume), is not a sign of weakness. It is a physiological tool. During a deload the body closes accumulated structural damage, hormone levels normalise, the central nervous system regenerates. The week after a deload is often the most productive of the entire training block, supercompensation becomes measurable.
3. Progression as the Only Compass
The only reliable indicator of productive training is progression, whether you achieve more weight, more reps or better technique at the same weight in subsequent weeks. Stagnation despite high volume is the clearest signal for insufficient recovery, not insufficient effort.
Practice: Hardgainer Training That Works
Step 1: Calibrate Volume
Start with 8 to 12 sets per muscle group per week, above MEV, allowing sufficient recovery. Increase only when performance, sleep quality and subjective recovery all remain stable. Add no volume when any one of these three signals turns negative.
Step 2: Prioritise Intensity
Execute every working set at RIR 0 to 2. If you could comfortably complete 5+ more reps after a set, it was too easy. Fewer sets, but every one counts.
Step 3: Schedule Deloads
Every 4 to 6 weeks: one deload week at the same weights but 60 to 70 % of normal volume. Expect measurable performance gains in the following week as supercompensation kicks in.
Quality Checklist Per Session
- All working sets executed at RIR 0 to 2
- No set performed with degraded technique due to fatigue
- Progression vs. the last session present (weight, reps or technique)
- Tired after the session, but not destroyed
- No persistent joint pain or overuse signals
Common Mistakes (and Better Alternatives)
| Mistake | Problem | Better |
|---|---|---|
| 20+ sets/muscle/week | Fatigue exceeds stimulus. junk volume, no growth | 8 to 12 hard sets at RIR 0 to 2 |
| 6 training days without a deload | Accumulated fatigue, stalling or declining performance | 4 to 5 training days + planned deload every 4 to 6 weeks |
| Increasing volume when progress stalls | The root cause (insufficient recovery) is amplified instead of addressed | Reduce volume, check sleep & nutrition, rebuild from there |
| Counting sets at RPE 6 | No sufficient mechanical stimulus, no growth | Increase weight until RPE 8 to 9 (RIR 1 to 2) |
| Avoiding deloads out of fear of muscle loss | No muscle loss during a deload, but performance drops without one | Anchor the deload as a fixed phase in the training plan |
Myth
“More training = more muscle.”
Fact
Precision + recovery = growth. The right stimulus followed by sufficient recovery outperforms maximum volume every time.
FAQ
How many sets per muscle per week are optimal for hardgainers?
As a starting point: 8 to 12 hard working sets per muscle group per week. This sits above MEV while allowing sufficient recovery. More advanced trainees can push to 14 to 16 if recovery signals (sleep, performance, mood) stay positive. Above 20 sets per week is junk volume for most natural hardgainers.
What exactly is junk volume?
Junk volume refers to sets that carry too little intensity to produce a growth stimulus, but still generate fatigue. Sets with RPE below 7 (RIR 3+) in a working set context typically qualify. They cost energy and recovery capacity without delivering a meaningful hypertrophic stimulus.
How do I know if I’m overtraining?
Classic signals: stalling or declining strength despite consistent nutrition, worsening sleep quality, chronically elevated resting heart rate, loss of motivation, joint discomfort without acute injury. If two or more of these occur simultaneously, volume or intensity needs to be reduced.
Will I lose muscle during a deload?
No. A deload week at 60 to 70 % of normal volume maintains the stimulus while reducing accumulated fatigue. Muscle loss only sets in after several weeks of complete training cessation. The week after a deload is typically the most productive, supercompensation only becomes visible once fatigue dissipates.
What is the SRA curve and why does it matter?
The SRA curve describes the three-stage adaptation cycle: stimulus (training), recovery (return to baseline) and adaptation (supercompensation above baseline). Applying the next stimulus before recovery is complete means training on a weakened system, cumulative fatigue builds. Waiting too long means the supercompensation peak is missed. Optimal timing sits between the two.
Can I really achieve more as a hardgainer with fewer sets?
Yes, if intensity is right. 10 sets at RIR 1 produce more hypertrophic stimulus than 20 sets at RIR 4. For hardgainers whose recovery capacity is already more limited, the stimulus-to-fatigue ratio is especially decisive. Less, but harder, followed by sufficient recovery, is the more efficient model.
What the research says
Four papers behind the claims on this page
The research on the dose-response relationship between training volume and hypertrophy is consistent: a moderate weekly volume is better for natural athletes than maximum volume. Intensity (RIR and RPE) and recovery are the decisive modulators of growth, and additional sets do not replace them.
- Meta-analysis: positive relationship between weekly volume and hypertrophy, but with diminishing returns and a plateau effect at high volume. Schoenfeld BJ, Ogborn D & Krieger JW (2017): Dose-response relationship between weekly resistance training volume and increases in muscle mass. J Sports Sci.
- Higher volume promotes hypertrophy, not necessarily strength; recovery remains the central limiting factor. Schoenfeld BJ et al. (2019): Resistance training volume enhances muscle hypertrophy but not strength in trained men. Med Sci Sports Exerc.
- Velocity-loss thresholds as a proxy for intensity: lower velocity loss (higher RIR) allows more volume at comparable adaptations. Pareja-Blanco F et al. (2020): Effects of velocity loss during resistance training on athletic performance, strength gains and muscle adaptations. Scand J Med Sci Sports.
- Submaximal intensities (0 to 50 % velocity loss) still show hypertrophic adaptations; confirmation that maximum exhaustion per set is not necessary. Rodiles-Guerrero L et al. (2022): Muscular adaptations in a 10-week submaximal velocity-based resistance training program. Int J Sports Physiol Perform.
What is not covered by the studies
The recommendation to calibrate volume against recovery signals instead of a target number is a practical derivation. The studies show the diminishing returns, but they do not give an individual threshold. You only find that one yourself, over weeks.
Practical takeaway: calibrate volume against recovery signals, not against a fixed set count. Intensity (RIR 0 to 2) is the non-negotiable factor.
Conclusion
“More training = more muscle”, a myth that costs hardgainers dearly. More volume without sufficient recovery produces accumulated fatigue, stalling performance and elevated injury risk.
What actually works: sufficient stimulus at high intensity, structured recovery phases via deloads, and progression as the only compass. Less, but harder, followed by consistent recovery, is the more efficient model for natural athletes.
Your body doesn’t need more sets: it needs the right stimulus, followed by sufficient recovery. Precision beats volume.
