So, I've been keeping track of my heart rate and noticed that my resting heart rate is usually between 50 and 55 bpm. I'm a 20-year-old guy, relatively healthy, and Im about 6'2 tall, weighing 74 kg. When I do high-intensity interval training, my heart rate can spike up to 150-160 bpm. Is this normal for someone my age and build, or should I be concerned about these numbers?

A resting heart rate averaging around 50-55 bpm can be normal for a healthy 20-year-old male, especially if you are physically active or an athlete, as regular exercise often leads to a lower resting heart rate due to increased cardiovascular efficiency. Reaching a heart rate of 150-160 bpm during High-Intensity Interval Training (HIIT) is also within normal ranges for vigorous exercise. However, if you experience symptoms such as dizziness, fatigue, or fainting, it would be advisable to consult with a healthcare provider to ensure there are no underlying issues. Otherwise, your heart rate appears consistent with a healthy, active lifestyle.
