Target Heart Rate vs Age
Karvonen Formula
Target HR = (Max HR - Resting HR) x Intensity% + Resting HR
The Karvonen formula is more accurate than simple percentage methods because it accounts for your resting heart rate (heart rate reserve).
Max HR = 220 - Age
Example Calculation
A 30-year-old with a resting HR of 65 bpm targeting 70% intensity.
- 01Max HR = 220 - 30 = 190 bpm
- 02HR Reserve = 190 - 65 = 125 bpm
- 03Target HR = 125 x 0.70 + 65 = 152.5 bpm
