Introduction
When it comes to building muscle, two main schools of thought dominate the fitness world: High-Intensity Training (HIT) and Volume Training.
Some swear by doing fewer sets at maximum effort. Others pack their workouts with multiple sets, reps, and exercises. But which approach is actually better for hypertrophy — gaining muscle size?
In this blog, we’ll break down both methods in a simple, scientific, and practical way — helping you choose what works best for your goals, body, and lifestyle.
What is High-Intensity Training (HIT)?
High-Intensity Training (HIT) is all about maximum effort in minimal time. Typically, it involves:
- 1 working set per exercise
- Performed to absolute failure
- With perfect form
- Usually full-body workouts
- Low training volume, but very high intensity
It was popularized by Arthur Jones (inventor of the Nautilus machines) and later championed by bodybuilders like Mike Mentzer and Dorian Yates.
Key Benefits of HIT
✅ Time-efficient
✅ Forces maximum muscle fiber recruitment
✅ Reduces risk of overtraining
✅ Easier recovery between sessions
Who is HIT For?
- Intermediate to advanced lifters
- Busy professionals
- Those with limited time or recovery capacity
What is Volume Training?
Volume Training, on the other hand, is based on total training volume = sets × reps × weight. This style includes:
- Multiple sets per exercise (3–6 or more)
- Moderate intensity (65–80% of 1RM)
- Higher total reps
- Often split routines (e.g., chest day, leg day)
- Trains each muscle group 1–2x per week
Volume Training is the standard in most bodybuilding programs, like Arnold Schwarzenegger’s legendary workouts.
Key Benefits of Volume Training
✅ Creates greater metabolic stress
✅ Offers more practice per movement
✅ Allows for variation and mind-muscle connection
✅ Ideal for muscle pump and endurance
Who is Volume Training For?
- Beginners to advanced lifters
- People looking for maximum hypertrophy
- Individuals who enjoy longer gym sessions
- Athletes with strong recovery abilities
What Does Science Say?
📊 Study Snapshot:
- Schoenfeld et al. (2016): Found that higher volumes generally produced greater hypertrophy, but only up to a point.
- Burd et al. (2010): Muscle protein synthesis plateaus after ~4–6 sets per muscle group per session.
- Hackett et al. (2013): Going to failure (HIT style) can be more effective in trained lifters than beginners.
✅ Conclusion:
Volume is crucial — but quality > quantity. Pushing to failure occasionally (HIT-style) can enhance growth, especially when intelligently programmed into a volume-based routine.
Which One Should YOU Choose?
Option A: HIT Approach
- 🔥 Train 3x/week
- Full-body or upper/lower split
- 1–2 sets to true failure
- Focus on progressive overload (more weight or reps each week)
- Prioritize form and recovery
Option B: Volume Training
- 🏋️♀️ Train 4–6x/week
- Push-pull-legs or bro-split
- 3–5 sets, 8–12 reps per exercise
- Use moderate effort (not always to failure)
- Emphasize variety and muscle tension
Hybrid Model: The Best of Both Worlds
For many intermediate and advanced trainees, a hybrid model works best:
- Use HIT-style sets for compound lifts (squats, deadlifts, bench press)
- Add volume sets for isolation exercises (curls, flyes, leg extensions)
- Include deload weeks every 4–6 weeks
- Track your performance and listen to your body
Final Thoughts
There’s no one-size-fits-all in fitness. HIT and Volume Training are tools, not religions. The best plan is the one that:
- Fits your schedule
- Matches your recovery
- Keeps you consistent
- Challenges your muscles progressively
Whether you like short, brutal sessions or long pump-filled workouts — commit, track progress, and enjoy the process.
