Key Takeaways
- Training volume = Sets x Reps x Weight - the key metric for muscle growth
- Progressive overload means gradually increasing volume over time
- Track weekly volume per muscle group for optimal results
- 10-20 sets per muscle group per week is ideal for hypertrophy
- Quality reps matter more than just increasing numbers
What Is Workout Volume?
Workout volume is the total amount of work performed during a training session, calculated by multiplying the number of sets by repetitions by the weight lifted. It's one of the most important variables for muscle hypertrophy (growth) and strength development.
Understanding and tracking your workout volume allows you to implement progressive overload - the gradual increase of stress placed on the body during training, which is essential for continued gains in strength and muscle mass.
The Workout Volume Formula
Volume = Sets x Reps x Weight
Example Calculation
If you perform 4 sets of 10 reps with 100 lbs on the bench press:
Volume = 4 x 10 x 100 = 4,000 lbs
This means you've moved a total of 4,000 pounds during that exercise.

Why Track Workout Volume?
Progressive Overload
Volume tracking is essential for progressive overload. By knowing your current volume, you can systematically increase it over time, ensuring continued muscle and strength development.
Prevent Overtraining
Monitoring volume helps prevent overtraining. Research suggests that exceeding optimal volume ranges can lead to diminishing returns and increased injury risk.
Optimize Recovery
Understanding your training volume helps you plan recovery periods appropriately. Higher volume requires more recovery time between sessions targeting the same muscle groups.
Optimal Volume Guidelines
For Muscle Hypertrophy
- Beginners: 10-12 sets per muscle group per week
- Intermediate: 12-18 sets per muscle group per week
- Advanced: 18-25+ sets per muscle group per week
For Strength Development
- Focus on lower rep ranges (1-6 reps)
- Higher intensity (80-95% of 1RM)
- Moderate volume (4-8 sets per exercise)
Frequently Asked Questions
Aim to increase volume by 2.5-5% per week. This can be achieved by adding reps, sets, or weight. A typical approach is to add 1-2 reps per set, then reset reps and add weight when you reach your rep target.
Not necessarily. There's an optimal volume range for each individual. Too little volume won't stimulate growth, while excessive volume can lead to overtraining and regression. Most people see optimal results with 10-20 sets per muscle group per week.
Both are useful. Tracking per exercise helps with progression planning, while tracking per muscle group ensures you're hitting optimal volume for muscle growth. Weekly volume per muscle group is generally more important for hypertrophy.
This calculator focuses on resistance training volume. Cardio is typically measured differently (duration, distance, heart rate zones). However, high-intensity cardio can impact your recovery capacity for resistance training.
For compound exercises like squats or bench press, count the volume toward all primary muscle groups worked. For example, bench press volume counts toward chest, shoulders, and triceps. Some people count it as 1 set for each, others as 0.5 sets for secondary muscles.
