⚡ CalcWolf Insight

Resting heart rate is one of the best indicators of cardiovascular fitness. Average is 60-80 bpm. Fit individuals: 50-60 bpm. Elite endurance athletes: 35-50 bpm. A decreasing resting heart rate over weeks of training is one of the most reliable signs that your fitness is improving.
