📐 Formula
💡 Practical Example
A lifter performing 4 sets of 8 on barbell squats at 225 lbs discovers their total tonnage is 7,200 lbs (3.6 tons) with an estimated 1RM of 280 lbs, setting a clear target to achieve 7,380 lbs next week for progressive overload.
📖 About Workout Log & Volume Load Calculator
Exercise Science, Biomechanics & Volume Load Metrology
Resistance training volume drives neuromuscular adaptations and mechanical tension:
- **
- NSCA Volume Load & Tonnage Formulas**:
Total Repetitions = Working Sets × Reps per Set
Volume Load (lbs) = Total Reps × Working Weight (lbs)
Volume Load (Tons) = Volume Load (lbs)2,000
- **
- Brzycki 1-Rep Max (1RM) Formula**:
1RM = Weight Lifted1.0278 - (0.0278 × Reps)
Relative Intensity (\%) = ( Weight Lifted1RM ) × 100
- **
- Standard Resistance Training Benchmarks**:
- Dumbbell Press: 4,320 lbs Volume | 1RM: 173 lbs (69.4% Intensity)
- Bench 5×5: 4,625 lbs Volume | 1RM: 208 lbs (88.9% Intensity)
- Deadlift Triples: 4,725 lbs Volume | 1RM: 334 lbs (94.3% Intensity)
- Squat 4×8: 7,200 lbs Volume (3.6 Tons) | 1RM: 280 lbs (80.4% Intensity)
How to Use This Calculator
Enter your Working Weight Lifted (Lbs) (e.g. 225 in lbs), Reps per Set (e.g. 8 in reps), Number of Working Sets Completed (e.g. 4 in sets), Rest Interval Between Sets — choose from 60 Seconds (Hypertrophy / High Density), 90 Seconds (Moderate Rest), 120 Seconds (2 Minutes - Strength & Power), Athlete Bodyweight (Lbs) (e.g. 175 in lbs), and Strength Training Benchmark — choose from Custom Workout Log, Squat Hypertrophy (4 sets × 8 reps @ 225 lbs) → 7,200 lbs Volume (3.6 Tons) | 1RM: 280 lbs (80.4% Intensity), Bench Press 5×5 (5 sets × 5 reps @ 185 lbs) → 4,625 lbs Volume | 1RM: 208 lbs. Results update instantly as you type — adjust any value to compare scenarios.
