Your personal output score: load × distance ÷ time. It rises when you carry more, go farther, or move faster — so you can see progress even when the pack weight stays the same. It's a training-load index, not a physics readout.
Ruck Power is a relative progress index for comparing your own sessions over time — not a medical or physics measurement. Units are normalized (load in lb × distance in mi ÷ hours). Data is saved on this device only. © 2026 Ken Hoyer / Body Plus Fitness.
