Calculate My Heart Rate

CalculateMyHeartRate provides a web‑based calculator that generates five personalized heart‑rate training zones based on the Karvonen formula. Users enter their age and optional resting heart rate, and the tool computes zones that reflect individual cardiovascular fitness rather than generic age‑based ranges. The calculator is aimed at runners, cyclists, triathletes, strength athletes, cardiac‑rehab patients, and anyone who wears a heart‑rate monitor. It also offers guidance on measuring resting heart rate first thing in the morning and lets users log their resting HR over time to track fitness improvements. What sets this tool apart is its use of heart‑rate reserve (max HR minus resting HR) to tailor zones, automatically updating as the user’s resting rate changes. The site includes explanations of each zone, tips for zone‑specific training goals, and options to use alternative formulas such as Tanaka, Nes, or Gulati for maximum HR estimation.
