Frequently Asked Questions
How do I measure my resting heart rate?
Take your pulse first thing in the morning while still lying down, before coffee or movement, and count beats for 60 seconds. Do this on a few days and average the readings.
What is the difference between 220−age and Tanaka?
220 minus age is the classic quick estimate; the Tanaka formula (208 − 0.7 × age) is often closer for older adults. The tool shows the estimated max for the formula you pick.
Should I train in one zone all the time?
No — a balanced plan mixes easy aerobic work in zones 2–3 with shorter threshold and interval efforts in zones 4–5, plus warm-ups in zone 1.
