Target Heart Rate & Training Zone Calculator
Find your optimal fat-burning and cardio training zones. Calculate your Maximum Heart Rate and ideal beats per minute (BPM) based on your age and fitness goals.
Optimize Your Cardio Workouts
If your heart rate is too low, you aren't improving cardiovascular health. If it's too high, you risk burnout or injury. This calculator uses standard physiological formulas to determine your Maximum Heart Rate (MHR) and breaks down the exact BPM ranges you need to hit for fat loss, aerobic endurance, and anaerobic performance.
