What this covers

Health & Body Tracking: the big picture

Health numbers only help when you can read them: what a blood pressure reading means, what heart-rate zone you're training in, what your BAC is, and how sleep debt adds up. BoringToolsKit's health calculators translate measurements into plain answers.

  • Normal resting blood pressure is around 120/80 mmHg.
  • Heart-rate zones are percentages of maximum heart rate.
  • BAC depends on drinks, weight, time, and sex; never drive after drinking.
