Kettlebell Session Density Calculator
How hard did you actually train? We benchmark your pace against measured reps-per-minute rates for 211 specific kettlebell variations — not generic RPE or MET values. Returns a 0–100 performance score, tier label, tonnage, calories, and exactly how many more reps it would take to hit the next tier. Nobody else has this data.
