As a fitness expert with a background in sports science, I can tell you that the time it takes for your heart rate to return to normal after exercise can vary greatly depending on several factors, including the intensity of the exercise, your fitness level, and your age. Generally, after moderate-intensity exercise, it might take anywhere from 15 minutes to an hour for your heart rate to return to its resting level. If you've engaged in high-intensity or vigorous exercise, it could take longer, potentially up to 24 hours, especially for those who are new to exercise or have lower fitness levels. To speed up the recovery process, it's important to cool down properly after your workout with a period of light activity or stretching. This gradual reduction in activity helps your body transition from the heightened state of exercise to a state of rest more smoothly. Additionally, staying hydrated and consuming a balanced meal or snack after exercise can also aid in recovery, as can getting adequate sleep and rest. Remember, everyone's body is different, and recovery times can vary. If you're concerned about your heart rate recovery or have any health concerns, it's always a good idea to consult with a healthcare professional. read more >>

The more fit you are, the faster the recovery. Your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute��a drop of less than 12 beats a minute is considered abnormal. This ��recovery heart rate�� is measured as part of an exercise stress test.read more >>
