German Volume Training (GVT), often called the 10×10 workout, is a classic high-volume strength and hypertrophy method that has stood the test of time in bodybuilding and athletic circles. Its roots go back to European weightlifting coaches in the 1970s, but it was popularized in the United States by Charles Poliquin, one of the most influential strength coaches in modern fitness.
The method is as straightforward as it is grueling: you perform 10 sets of 10 repetitions of a single compound exercise, typically with a weight around 60% of your one-rep max. By dramatically increasing training volume, the program forces your muscles to adapt, leading to size and strength gains. While the formula looks simple, the intensity, discipline, and recovery required to succeed make it one of the most demanding training systems.
What is German Volume Training?
German Volume Training is a high-volume resistance training protocol designed primarily for muscle hypertrophy. Unlike traditional programs that emphasize progressive overload through increasing weight, GVT emphasizes total time under tension and cumulative fatigue.
- The program is structured around 10 sets of 10 reps for one primary movement.
- Rest intervals are kept moderate, usually 60–90 seconds, which adds to the metabolic stress.
- Accessory work is often included, but the backbone of the program is the brutal 10×10 structure.
The simplicity is deceptive: most lifters fail not because of strength limitations, but because of the endurance and mental toughness required to push through such high volume with strict form.
How Does GVT Work?
The logic behind GVT comes from the principle that muscle growth is heavily influenced by training volume. By pushing a muscle group through 100 total reps at a challenging load, you create:
- Mechanical tension: The repeated effort at a moderately heavy load stresses the muscle fibers.
- Metabolic fatigue: Short rest periods prevent full recovery, amplifying muscle pump and metabolic stress.
- Fiber recruitment: Early sets recruit slow-twitch fibers, while later sets, when fatigue sets in, force recruitment of high-threshold motor units.
Together, these mechanisms drive hypertrophy, which is why GVT has earned the reputation of being a “shock method” for breaking through plateaus.
Where German Volume Training Does Work
While not a long-term program, German Volume Training can be highly effective for lifters who want to push their hypertrophy progress. Some benefits include:
Hypertrophy Gains: The sheer volume shock can spark muscle growth, provided nutrition and recovery are sufficient.
Bodybuilding Phases: For intermediate and advanced lifters who need hypertrophy-specific phases, GVT can be useful. The slow tempos and high volume can drive new adaptation and break plateaus.
Mixing Things Up: Sometimes the brutality of 10×10 squats or bench press is exactly the disruption needed to force adaptation. While painful, the shock can reignite progress if your training has grown stale.
Short-Term Over-Reaching: For advanced trainees—especially athletes under 35 with strong recovery capacity—GVT can be used as a short-term over-reaching strategy (7–14 days). When followed by a deload, it may unlock new growth.
Example German Volume Training Routine
A classic GVT program is usually split into upper and lower body days with a focus on compound lifts. Below is a sample 5-day routine:
Day 1: Chest & Back
- Bench Press: 10×10 (60% 1RM, 60–90 sec rest)
- Pull-Ups (weighted if possible): 10×10
- Incline Dumbbell Fly: 3×12
- Barbell Row: 3×12
Day 2: Legs & Abs
- Squats: 10×10
- Romanian Deadlifts: 10×10
- Hanging Leg Raises: 3×15
- Weighted Crunch: 3×20
Day 3: Rest or Active Recovery
Day 4: Shoulders & Arms
- Overhead Press: 10×10
- Barbell Curls: 10×10
- Skull Crushers: 10×10
- Lateral Raises: 3×12
Day 5: Legs (Variation)
- Deadlifts: 10×10
- Front Squats: 10×10
- Calf Raises: 4×15
- Ab Rollouts: 3×12
Days 6 & 7: Rest
This type of routine is typically run for 4–6 weeks before switching to a lower-volume, heavier-load program.
What the Research Really Says About 10×10
In 2018, the study Effects of a 12-Week Modified German Volume Training Program on Muscle Strength and Hypertrophy—A Pilot Study examined the classic 10×10 German Volume Training protocol compared with a reduced-volume 5×10 protocol.
The results were surprising for many coaches who had long considered GVT a “gold standard” for hypertrophy:
- No major difference in hypertrophy or strength outcomes between 10×10 and 5×10.
- Upper body (bench press) slightly favored the 5×10 group.
- Lower body (squat/leg mass) showed a slight edge toward 10×10—but not statistically significant.
- Interestingly, from weeks 6–12, the 10×10 group lost leg mass, suggesting possible overtraining of the lower body.
Takeaway: A full 12 weeks of 10×10 appears excessive, and hypertrophy gains are not superior to a more moderate 5×10 approach. If you’re going to use GVT, keep it under 6 weeks.
Practical Recommendations
If you’re curious about German Volume Training, here’s how I would approach it today:
- Who should try it: Intermediate/advanced lifters with 2–5+ years of training experience, primarily bodybuilders or those chasing hypertrophy.
- Duration: Maximum 4–6 weeks for hypertrophy phases. For over-reaching strategies, just 1–2 weeks before deloading.
- Volume ramp-up: Don’t jump straight from 3×10 to 10×10. Progress week to week (e.g., 5×10 → 7×10 → 10×10).
- Frequency: Use sparingly—1–2 phases per year at most.
- Program design: Consider upper/lower splits over body-part splits for better balance and recovery.
- Testing progress: Track girth measurements and bodyweight before and after, rather than expecting immediate strength improvements.
Why I Wouldn’t Use GVT as a Primary Program
Because intensity (load) must be reduced to survive the high volume, absolute strength often stalls or even regresses during GVT phases. Strength tends to return after recovery, but this makes it a poor choice for athletes prioritizing performance.
Recovery Limitations
Most lifters simply can’t tolerate the recovery demands. Sleep, nutrition, and stress management must all be dialed in for GVT to be productive.
Time Cost
Performing 10 sets per exercise is time-consuming. Workouts typically shrink to just 1–3 main lifts because the volume is overwhelming, making it inefficient for busy professionals.
My advice as a coach:
Interestingly, Charles Poliquin was one of the only major coaches who actively promoted GVT in the early 2000s. Outside of his influence, few in the evidence-based fitness world continued to advocate for it.
Having experimented with German Volume Training myself and with clients, I’ve reached the same conclusion as the research:
- I would rarely, if ever, prescribe 10×10 long term.
- A 5×10 approach achieves nearly the same results without the recovery burden.
- For most lifters, there are better, more sustainable hypertrophy methods available.
Frequently Asked Questions
1. Is German Volume Training good for strength or just size?
GVT is primarily a hypertrophy method. While strength gains can occur, it is less effective than lower-rep, heavier-load strength training.
2. Can beginners try GVT?
Not recommended. Beginners should focus on learning technique, building foundational strength, and gradually progressing volume.
3. How long should I follow GVT?
Typically 4–6 weeks. Longer cycles often result in diminishing returns and excessive fatigue.
4. What is the ideal rest time between sets?
Between 60–90 seconds. Too long reduces metabolic stress; too short may cause premature failure.
5. Do I need supplements for GVT?
While not mandatory, supplements such as whey protein, creatine, and BCAAs may support recovery and muscle repair due to the extreme workload.
Final Thoughts
German Volume Training holds a legendary place in bodybuilding lore, but the research and real-world experience both suggest it’s overrated as a long-term program. While 10×10 can provide a shocking stimulus and temporary hypertrophy boost, 5×10 appears equally effective with far less recovery cost.
For most lifters, GVT is best treated as a short-term tool, not a lifestyle. Use it sparingly to break plateaus, experiment with training volume, or as a strategic over-reaching phase. Beyond that, there are more efficient and sustainable hypertrophy methods available.
