> resting heart rate being in the 113-120 bpm That seems insanely high
It's not "insanely" high. And blanket statements like this can cause undue alarm. If you're worried about an elevated resting heart rate, go get an ECG done. Don't let random people on the internet talk you into health anxiety.
So for someone who is say 30, your maximum rate is ~187. But a rate over 90 when resting is considered outside normal levels.
If you have no history of cardiac disease and aren't taking any medications that would cause an increased rate, if your resting rate is 113-120, you need to be checked.
