Training volume (volume) — sets, repetitions, tonnage

Short answer: Volume, not just weight, is the main factor for muscle growth (hypertrophy). • There is a "sweet spot" of volume (MAV), which is between the minimum for maintenance (MEV) and the maximum for recovery (MRV). • Systematically increasing volume within a training cycle (mesocycle), followed by a deload week, is key for long-term progress.

Training volume is the total amount of work performed during a workout or over a specific period, measured by sets, repetitions, and weight, which is the primary driver of muscle hypertrophy.

What exactly is training volume?

In its simplest form, training volume is a mathematical expression of the work done. There are three main ways to measure it: 1. Number of working sets: This is the most common and practical method, popularized by experts like Dr. Mike Israetel. Here, we only count "working" sets for a given muscle group per week. A working set is one that is close enough to failure (usually with 1-4 repetitions in reserve, RIR 1-4) to stimulate growth. Warm-up sets are not counted. 2. Total number of repetitions (Load Volume = sets x reps): This method accounts for the total number of repetitions. For example, 5 sets of 10 reps equal 50 reps. It's useful but doesn't account for intensity (weight). 3. Tonnage (Tonnage = sets x reps x Weight): This is the most precise method, multiplying sets by reps and by the weight used. If you do 3 sets of 8 reps with 100 kg on the squat, your tonnage is 3 x 8 x 100 = 2400 kg. This method is excellent for strength athletes but can be misleading when comparing exercises with different ranges of motion. For hypertrophy purposes, measuring the Number of quality working sets per muscle group per week has become the most effective and easy-to-track metric. In this context, Dr. Mike Israetel introduced three key concepts:

• MEV (Minimum Effective Volume): The minimum volume needed to maintain muscle mass, and sometimes for minimal growth in beginners.
• MAV (Maximum Adaptive Volume): The optimal volume at which you achieve the best growth. This is not a fixed number but rather a range that changes as you progress.
• MRV (Maximum Recoverable Volume): The maximum volume your body can recover from. Training above this threshold for an extended period leads to overtraining, regression, and risk of injury.

How do MEV, MAV, and MRV work in numbers?

Let's illustrate these concepts with a specific example for a muscle group like the chest. The numbers are approximate and vary greatly depending on experience, genetics, and lifestyle (sleep, nutrition, stress). Assume you've been training for a while and want to optimize chest growth. Your training cycle (mesocycle) of 5-6 weeks might look like this: * Week 1 (Start of cycle - MEV): You start with 10 working sets for the chest per week. For example: * Monday: Bench press (4 sets) + Dips (3 sets) = 7 sets * Thursday: Incline dumbbell press (3 sets) * The feeling is light, you barely feel any muscle soreness. This prepares the body for the following weeks. * Weeks 2-4 (Progression towards MAV): Each week, you increase the volume. * Week 2: 12 working sets * Week 3: 15 working sets * Week 4: 18 working sets * In this range (12-18 sets), your MAV is likely located – the sweet spot. Workouts are tough, you have good muscle soreness, but you recover fully before the next session. Your strength is increasing or at least maintained. * Week 5 (Functional overreaching - towards MRV): You decide to "push" the system to induce greater adaptation. You increase the volume to 20-22 working sets. Here you are at or slightly above your MRV. * Feeling: Constant fatigue, joints start to ache, muscle soreness doesn't fully disappear between workouts. Your strength is likely starting to slightly decline. You cannot sustain this volume for long. * Week 6 (Deload - unloading): You drastically reduce the volume to below MEV, for example, 6 working sets with lighter weights. This allows the body not just to recover, but to supercompensate, becoming stronger and bigger for the next cycle.

How to use it?

Volume management is a periodization process that doesn't allow you to train at your maximum volume (MRV) constantly.

Volume management is a periodization process. You cannot train at your maximum volume (MRV) constantly. * For hypertrophy (muscle gain): Use the principle of progressive overload through volume. Start a mesocycle with volume around your MEV and increase it each week (by 1-2 sets per muscle group) until you reach your MRV. Then, do a deload week. * For strength: Volume is still important, but intensity (percentage of your one-rep max) is leading. Here, tonnage is a better indicator. Often, the total number of reps is lower, but the weights are heavier (e.g., 5x3 instead of 3x10). * During a calorie deficit (cutting): Your recovery capacity is reduced. Your MRV drops drastically. The goal here is to preserve muscle mass. The best strategy is to maintain volume around your MEV, aiming to keep intensity (weights) as high as possible. Attempts to increase volume during a diet often lead to muscle loss.

Comparative table of volume markers

Marker	Approximate sets/week	Primary Goal	Application
MEV (Minimum Effective)	~8-12	Muscle maintenance	Start of cycle, deload, dieting period.
MAV (Maximum Adaptive)	~12-20	Optimal growth	The main part of the training cycle.
MRV (Maximum Recoverable)	~20+	Functional overreaching	The last week before deload.

What are common mistakes and misconceptions related to training volume?

Even with an understanding of the concepts, many trainees make mistakes that sabotage their progress.

1. Should I count warm-up sets towards my volume?
No. Warm-up sets are for preparing the muscles and nervous system, but they are not intense enough to cause hypertrophic adaptation. Count only working sets that are close to failure.

2. How do I calculate volume for compound exercises like squats, which work multiple muscle groups?
For compound exercises, count the sets for the primary moving muscle group. For example, in squats, count the sets primarily for the quadriceps. The glutes and adductors receive stimulus, but it's secondary. You can count them as "half a set" (0.5) for these assisting groups.

3. Does volume from cardio or metcon workouts (like in CrossFit) count?
For hypertrophy purposes, generally not. Although high-intensity metcons create overall fatigue and tax the muscles, the stimulus is often not as specific and focused as in traditional strength training. However, they contribute to the overall stress on the body and can reduce your MRV.

4. Is the volume for small muscle groups (biceps, triceps, calves) the same as for large ones?
No, smaller muscle groups typically require and recover from less total volume. While quads might handle 20+ sets per week, for biceps, 10-14 quality sets are often sufficient for good growth.
