Solve Target Heart Rate Zone
Heart-rate zones are estimates and methods vary. Use your chosen intensity range consistently.
Formula: Estimated maximum heart rate β 220 β age; Target zone = maximum heart rate Γ selected intensity
Small input differences can affect an estimated health result, especially for circumference-based or energy-need formulas. Measure consistently and avoid false precision.
Compare the displayed answer with the formula above so you can see which inputs are driving the estimate.
