Hello, I am 19 years old, 6 1, 180 lbs, and I have a very low body fat percentage. In other words I am very strong and very athletic. As for my concern, I have a resting heart rate of 108. My piers who are equally as athletic tend to have resting heart rates of 45-60 bpm. My question is, should I be worried? I do have anxiety issues and have had multiple anxiety attacks in the past couple of years but to be honest I never had them addressed. Could it be anxiety effecting my high heart rate? Or perhaps something else? Thanks.
