Heart Rate

My resting heart rate is 64 bpm.
My active hear rate is 192 bpm.
my target heart rate is supposed to be between 103-154, but it can go over that. It just says it shouldn't exceed 205 bpm.

Honestly, I don't know why having a lower heart rate would be good. I like working out, and the training I do is pretty intense. I do understand that doing that much work with your heart might be bad for it, but I really do like working hard. It just makes me feel alive. I don't think it'd be a bad idea if I lowered my activity level, but if I had the choice, I'd like to keep doing what I'm doing

thanks for reading.
