Is my resting heart rate of 36 bpm ok?

For reference, a "normal" heart rate for most people is 60 - 100 bpm. You probably already know that.

Yours is very low. Most people, as mentioned above, are 60 bpm or above. However, with only a few months of intense training, a moderately athletic person could potentially reach a point of having such a low heart rate.

If you've been training intensely, particularly aerobic exercise like running or cycling, it's possible that your low heart rate is just a result of your heart's improved ability to move blood through your body. If that's the case, good job. You're well-conditioned, and assuming you have no symptoms of bradycardia (a low heart rate) such as dizziness or light-headedness upon standing, there's no great cause for concern.

If, however, you experience any such symptoms, or you are not in Excellent athletic shape, you should really consult a physician about your slow pulse, as it could be an indicator of serious underlying problems. Un-athletic people should not have heart rates in the 30's.
