How It Works

How Training Volume Is Calculated

Formula

Volume = Sets x Reps x Weight

Total workout volume sums this across all exercises.

Why Volume Matters

Training volume is the primary driver of muscle hypertrophy. Research shows that 10-20 sets per muscle group per week is optimal for most lifters. Tracking volume ensures progressive overload over time.

Worked Example

5 exercises, each with 4 sets of 8 reps at 135 lbs.

sets = 4reps = 8weight = 135exercises = 5
  1. 01Volume per exercise = 4 * 8 * 135 = 4,320 lbs
  2. 02Total volume = 4,320 * 5 = 21,600 lbs
  3. 03Total reps = 4 * 8 * 5 = 160 reps
  4. 04Total sets = 4 * 5 = 20 sets
