Training volume
Training volume
Definition
Training volume represents the total amount of work performed in a session, week, or cycle. It's one of the 3 fundamental pillars of programming, alongside intensity and frequency.
In strength training, volume is the #1 driver of hypertrophy. The more effective sets you do, the more growth stimulus you produce.
💡 Volume ≠ weight lifted. A set of 12 reps at 60 kg represents more volume than a set of 3 reps at 100 kg, despite the lower load.
How to measure volume
3 main methods:
1. Effective sets per muscle/week
Simplest and most used method. Only count sets close to failure (RIR ≤ 3).
2. Total tonnage (volume × load)
Sets × Reps × Load = Tonnage. Relevant to track progress on heavy movements (powerlifting).
3. Relative volume load (by % of 1RM)
To compare different loads by standardizing intensity. More complex but more accurate.

⚠️ Beyond 25 weekly sets on a single muscle, studies show a plateau or regression due to inability to recover.
MEV, MAV, MRV: the 3 zones
Concept popularized by Dr Mike Israetel:
Ideally navigate between MEV and MAV, occasionally pushing toward MRV to stimulate new adaptations.
How to progress on volume
Classic method: increase volume across a mesocycle, then deload to allow supercompensation.

Key takeaways
Training volume is the main driver of hypertrophy. Aim for 10-20 effective sets per muscle per week, flirting with your personal MAV. Progressively increase over 4-6 weeks, then deload. Volume without intensity = few results. Intensity without volume = little stimulus. Balancing both makes the difference.

Type I fibers (slow-twitch) are endurance-oriented muscle fibers. Resistant to fatigue, they sustain prolonged efforts.
Type II fibers (fast-twitch) are powerful muscle fibers optimized for explosive efforts. Essential for strength and power.
The Upper/Lower program divides training into upper body and lower body sessions over 4 days per week. Perfect balance between frequency (2x/week) and volume for all levels.
VO2 max is the maximum amount of oxygen your body can use during intense exercise. It's the gold standard of cardiovascular fitness.
