When should your heart rate return to 120 after working out?

Your heart rate should ideally return to around 120 beats per minute within 10 to 20 minutes after a moderate workout, depending on your fitness level and the intensity of the exercise. Well-conditioned athletes may experience a quicker recovery, while those who are less fit may take longer. Factors such as hydration, temperature, and overall health can also influence heart rate recovery. Monitoring your heart rate regularly can help you assess your cardiovascular fitness over time.
