About the horsepower calculator
Tip: To calculate based only on your personal records, leave Music and Training days at their defaults (No music and 0 days) and set Skipped leg day to No. these options cancel each other out and will be more realistic.
Did you know? A horse can hit roughly 15 horsepower at peak (for short bursts).
The original horsepower unit was invented by James Watt to help price steam engines by comparing how many horses they could replace.
Our calculator’s formula weights how much each muscle group works in each exercise, and how much that group contributes to pushing a car. Using your personal records, the result estimates your momentary peak horsepower output.
