Target Heart Rate Calculator — Fórmula
## 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**
**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**
Ejemplo Resuelto
A 30-year-old with a resting HR of 65 bpm targeting 70% intensity.
- Max HR = 220 - 30 = 190 bpm
- HR Reserve = 190 - 65 = 125 bpm
- Target HR = 125 x 0.70 + 65 = 152.5 bpm
