Frequently asked questions
- How is max heart rate calculated?
- The most common formula is 220 minus your age in years. For a 30-year-old that gives 190 bpm. More precise formulas exist (e.g. Tanaka: 208 - 0.7×age) but 220-age is the standard starting point.
- Is it safe to exercise at my max heart rate?
- No — maximum heart rate is a ceiling, not a target. Most training happens at 50–90% of MHR depending on the zone.
